hi i just bought a 1983 280 zx i replaced the tps because the car was stalling out and i was told that would fix it. it didnt when i try to turn the key nothing happens after 20 or more times sometimes it will start.and stall out. the volt meter for the battrry goes up and down.please help please

You have a couple of issues going on.

1) check the connections between the battery and the starter if they are good...

2) have your starter tested-it probably need new brushes.

When the car turns over every time you turn the key, go to the next issue.

Check for vacuum leaks in the intake plumbing(with the car running spray WD40 around the intake hoses, if the idle rises, you have a leak that could cause or contribute to the problem.

Starts and stalls makes me think of intermittant fuel supply. Are you sure that you are getting fuel to the injectors?

NurseLaura and I have had similar issues with our ZX's and found success (limited in my case) after cleaning the fuel system, from tank to rail.

How long was this car sitting around before you bought it? When was the last time the fuel filter was replaced? How much junk is sitting in your tank/lines?

i took all the conectors off and cleaned them stll nothing. the fuel light comes on orange. i have a digital dash , and sensor comes on but when i turn the key all digital dash lights go out ecept the orange fuel light and sensor light.i changed the fuel filter. but i am concerned about the tps because i was told it was just changed before i bought it and it had to be set up by a mechanic. please help me i love my z and i would love to drive it. its killing me w

driving my other cars and the only car i want to drive is my 1983 280zx. my wifes car is a 2003 crysler sebring and my other car is a 1995 sunfire. please someone help me get out of the sunfire.

thank you

wont even turn over now. just the two warning lights for fuel and sensor. can hear clicking under my passenger dash think its my fuel pump . my hanes manual wont be in till next week . any ideas

thanks mark

Ignition relay?

Have you placed the battery on a charger in all this time you have been trying to start it? If not, and the clicking only happens when you are trying to crank the engine, I believe the sound you hear coming from under your dash may be your starter solenoid. It's not really under the dash but some without experience might think so. Not sure if you qualify or not at this point. Without enough juice to crank the engine, the solenoid will often chatter.

If the TPS was replaced by a certified mechanic, I would focus elsewhere. There is a possibility that something was knocked loose after the fact so check any electrical connections on near or around the replaced TPS, and any other items that might have been removed to make it easier for the mechanic to work.

iam going to try ign. relay,fusable links, and checking my starter

thanks mark

where is the ing. relay located there are alot of relays

The fuel pump is located in back, next to the gas tank, so that is not the clicking you hear.

I've attached a photo out of my FSM, perhaps it will help with your problem.

If you would like, I will email you all 56 pages from my manual, PM me if you want to take this option. Our cars are different years, some things WILL be different, but it may send you in the right direction.

If you haven't yet, get yourself a factory service manual (FSM), it is much better than Haynes or Chilton, although those are good references to have as well.

thanks everyone for all your help. Zcar owners RULE.replaced my ing. starts every time. now i tryed adjusting my tps very touchie it idls great but when i take it out on the road it kicks and bucks. i have spark plug wires comming tommorow. i hope thats it. any other sugg. thanks again to everyone who helped me along i never would have had the courage to do it on my own without your support.Zcars rock
