HI? my car starts up just fine and idle in park and nuetral gear just fine without i pressing on the gas. But when i press on the gas when it get to a certain point the engine shakes. the shaking also occur whe it in drive or reverse position and even when am test driving the car i feel the engine shake. with my foot on the brakes and car in reverse or driving gear, engine still shakes. i changed my spark plugs and spark plugs wire but did not change the distributor cap and rotor. i dont know what is going on? maybe i must have screwed up with my firing other or what. pls what is going on with my car and what is the firing order from the distributor to the engine. distributor firing order picture will be very helpful to me, so i can trace each cable from the distributor to the the correct spark plug. When i drive the car or just rev it in driving gear or in park/neutral gear at certain point it backfires like pop pop. help me pls and thanks for you help.

thanks for the ideas. i will try to see where exactly the sound it coming from. when driving the car, there is no sound. the sound only occurs when shift from park to reverse and drive. only when shifting/changing gears that when i hear the sound

hi and how are you? from park to reverse i hear a knocking or banging sound coming from under the car. the sound also occur when changing from reverse to drive. What could it be. my car is automatic 76 280z. also i have another question. is it a good idea to swap my car from automantic to manual? if yes what might be the cost to do the swap i.e include parts and labor. What parts do i need to do the swap.

i saw that relay and i believe it the feul pump relay

Thank you all for the great input. when i wrote my thrread i forgot to mention that, there is a relay close to the fuse box (i believe it the ignition relay. it used to be a big one and it mounted plug in side facing up but i change it coz i thought it was the problem. so now i have a small one). this relay is blue in color. when the key is on the off position in the ignition with the wiper switch on it makes noise but when i turn the key to on position with the wiper switch still on it stops making noise. if i have the wiper switch off and the key off it doesn't make noise. pls i need cable color for the under d dash. i want to know which cable/wire color and size that goes where. because my signal are not working, no horn, no interior light and no heater. all these things are not working. i can turn the headlight on and off just (car running and car not running). where can i buy an accessory relay or a horn relay for this car (76 280z) I was looking at the computer today, i saw two white cables that comes from the computer harness pin/head that snap to the computer and they are just hanging. two white cable.

thanks for your input. Pls help me with color of wire that goes to fuel pump, fuel pump relay, and wiper switch.

Thanks i kind of had the same feeling but my problem was, i don't the cable/wire coloring. which color cables goes to the ignition switch and which color cables goes to the turn signal/trafficating switch and the wiper and headlight switch. thanks

Thanks for your inputs. the cable/wire are in good shape. i need to check under the dash to see how they look

Thanks for this info. i will download the fsm. I have a repair manual in the garage. i will do as you mention about using the fuse box cover and locate what goes where and i will get back to you. thanks

HI and how are you? my 76 280z has some major electrical problems and i need great ideas on how to go about to fix these problem. The car starts and runs great. the headlight turns on and the hazard light also turns on. But the signal doesn't work, the interior light doesn't work, the radio is not working, the windshield wipers are not working, the heater fan is not working. to sum this all up, all these items i mentioned above, i believe there is no power going to them. Is there a main relay that controls all these items? i checked, cleaned and tested my fuse box and this is what i got. The side that control all the above items on the fuse box is not havig power. with my test light my test light was not lighting but when i tested the other row of fuses most of them light up only one or two did not light up. What can cause this issue? is there a break or circuit point that send power or allow power to go to this side (accessories) of the fuse box? In other to start the car and turn the fuel pump on, i will have to turn the wiper switch on if not the car will not respond to any thing. But with the wiper switch on the car turn on and start up and power goes to the fuel pump. When the car is running and i switch back the wiper switch to off the car dies. major problems i need a major help. pls help. when i got this car, it wasn't runing or starting but i have got it to the point that it starts and runs. i did some injectors job, complete brake job and many more to get the car to the condition it is today. thanks you for very much for the time spent to read my thread and helping me figuring out what causes this issue and fixing it.

Hi? my 1976 280z gas tank is bad but i found a 1978 280z gas tank in good shape. is there any way i can make the 78 280z gas tank work and install onto my 76 280z. i noticed that the 78 has a small pipe (gas filling pipe. the pipe that the gas goes thru to the tank. ) the pipe for the 76 is bigger. If i can use this tank pls what do i need to do to make it work out and install it. thanks

i have replace the fuel pump but still is the same problem. i figure this out because when i used a longer fuel hose and connected to a portable gas tank, the fuel pump was pulling the gas and the car starts and stays running but when it hooked up to the fuel tank the car doesn't start. how do you take out the d sending unit when the tank is still on the car. how can i access the tank through the trunk?

my fuel lines are ok and i dont know the interior condition of the tank but i know for sure my fuel pump cannot suck the gas out of it. it like something is blocking the d pipe where the gas suppose to come when the fuel pump draws or pull it. can i get step by step instructions on how to clean the gas tank and keep my sending unit in good working condition.

Hi and how are you? my 76 280z gas tank is bad. the pump cannot get fuel out of it to send up to the engine. what should be my next step? buy a new or used tank or clean up the tank? if cleaning up the tank is the best and cheapest way to go, how do i go about cleaning the tank and the sending unit? after cleaning will i have to replace the sending unit with a new one? pls give me ideas pls. i am a student and trying to restore this car. i work on it myself because i can't afford to have a mechanic to come work on it. i am looking for the cheapest and reasonable way to fix my gas tank and have it working fine. thanks

Hi? my car starts and runs for seconds and dies. so yesterday i worked on car and this is what i observed. i did a fuel pressure check. when i turn the key on the pressure build up to 39 psi and when i start the car the pressure slowly goes down and when it reach to 10 psi the car dies. Second test, i went to the store and bought me a long hose, i disconnect the short hose from the fuel pump and i connected the long hose to the fuel pump. i took the long hose and put it into the nozzle of the gas container ( container that we use to buy gas when you run out gas on the road) i turn the car on and the guage reads 35 psi. I turned the key to start and car started and stayed running till the gas in the container runs out and fuel pressure stays at 35 psi the entire time. When the gas in the container ran out, i went and buy another one gallon and hook it back up. but this time i did not get any fuel pressure reading on the gauge and i tried to start the car, it turns but no start. i can hear the fuel pump but it sounds different. I hooked the fuel pump back to the car gas tank and still no pressure. What next should i do? how do i clean the fuel pump? how do i clean the gas tank without having to remove it? Is there a filter in the gas tank that i can take out and clean? Thanks

Hi? my 76 280z was starting just fine and stays running till i shut it down. but after i drained the radiator and put in new coolant, change motor oil and i removed the stock intake and i put in a new air intake that i bought off eBay. i also empty the gas tank and put in five gallons of new gas. since then the car starts and idle for about five to ten seconds and dies. when it start it runs between 1000 and 2000 RPM. When i push the gas pedal it sputter or backfires. it sounds like pop pop and dies. it also dies even if i did not push the gas pedal. I can hear the fuel pump running. When ever it dies, when i turn the key it start right back up and runs and dies again. when it dies it dies slowly. I don't know what going on. Pls help thanks

Thanks for all the ideas. i will try them this week.
