An ignorant question about fuel injectors

[MEZZZ]

Does it matter which way the connector part of the injector is facing? I cant remember for sure which way mine were all facing when I removed them 10 days ago. I made a mental note but it seems my photographic memory isnt what it used to be

I could swear that 1-2-3 were facing towards the rear of the car, 4-5 the front and six towards the rear again.

Honestly, I am not sure if it even matters. I tried to look at some photos and have seen them turned all one way and other photos where they are going in opposite directions.

I carefully marked the wires while removing them and when I soldered new wires, I made sure that I didnt cross anything up. Any help is appreciated.

lay the harness around the injectors, that should tell you where they go.

I actually don't think there's any kind of set pattern on which way the injectors face. You just want to make sure that they are facing in such a way that you can get the connectors on and off of them easily without interference from the fuel rail, pressure regulator, etc. I also make sure I don't cross the wires when I solder on new connectors but it wouldn't really matter since all the connectors do is complete a ground.

Thank you. Stephen, I did the same thing wehn soldering, I marked each wire with a piece of tape so to make sure not to cross them. I read once it didnt matter which went to what side, I figure it if did, they wouldnt have made them both black.

The only thing lacking in that kit I bought were the rubber boots that go down over the connector. I could not find them anywhere. My old ones were dry, cracked and rotted, one reason I wanted to replace them. In searching online, I came across a link to a Jaguar site and saw a picture of a guy that used heat shrink tube in place of the rubber boot. Long story short, I did this and it turned out great. Very tight seal around the connector. Then I took a smaller diameter over that and shrunk it around the wire nice it tight, then finally another 6 inch piece over the whole thing.

I ended up putting the injectors facing the center of the motor, 3 one way, 3 the other.

Thanks again.

We did a thread on connectors a while back. I got the rubber boots from the junkyard along with the connectors. http://www.classiczcars.com/forums/showthread.php?t=22929

Thanks for the link Stephen, I remember reading that one awhile back in one of my many, many searches on here. Hopefully, the heat shrink wrap holds up, it appears to be extremely tight around the base of the connectors.

Pics of heat shrink please!

Ok, see if I can talk my wife into using her new camera

That wasnt too bad...3 minutes later and here they are...isnt technology wonderful? Here you go Dan,

Not the best shot, I tried to get closer and it would get a bit fuzzy, havent played with her new Sony 7 meg much and dont ahve the patience either...

I went to Advance Auto and picked up a pack of assorted heat shrink tube, the largest(about 3/4 inch wide) was blue, would have preferred black but didnt feel like driving all over looking for it. It had a 3 to 1 shrink ratio and tightened up very nicely around the base but didnt shrink tight around the top of the wire. So I slipped another piece over the blue, and shrunk that up tight around the wire, each piece I cut to about 2 inches in length.

Then I used the black 6 inch long piece to go over everything after I soldered the new connectors on.

It beat the he!! out of going without since I couldnt find the rubber boots.

Unfortunately, I still cant get her to fire. I took the kind of stupid step of replacing alot of parts, but from the looks of them, they needed it anyway, i.e, plugs, wires, cap, rotor, fuel filter, all vacuum and injection hoses. Since I had the rail off doing the injectors, I replaced all the hose and used all new injection clamps and bought a new fuel pressure regulator for the heck of it. Then I bought a new ignition coil (MSD Blaster 2), it happened to be on sale and then today splurged for a new battery as mine didnt seem to crank too long before running out of juice. Brought it today to be tested, told me it might take an hour, thought screw it, my time is worth something, just give me a new one.

Now I have printed out the fuel injection manual and will start my education on the system. So far I have checked each plug for spark (have it), pulled the line past the filter and have fuel and pressure as it comes squirting out. It fires with starting fluid so I am thinking it is fuel related. I am suspect now of possibly the fuel relay or ECU. I have read the F.I. manual and will begin going through the trouble shooting section trying to figure it out.
