22re injector problem

Hardline Crawlers - Rock Bouncer Builds, Tech & Off-Road Trail Talk

Help Support Hardline Crawlers:

It should be on the passenger side a silver finned box unless its a newer harness I don't think those have them.
 
do you have the circuit open relay on the passenger hooked up yet? if the whole system ran in the other rig then you either hooked up something wrong or forgot to hook something up... as far as i know all the circuit open relay does is control the fuel pump. im fairly certain it does not control the pulsing of the injectors

FYI there is no silver/aluminum rististor box in the newer rigs...

how much of the harness did you chop up? and did you swap in the fuel tank/pump/sender/complete intake and wiring,computer sensors ect ect...

I didn't chop up ANY of the engine bay harness. The only thing I have "chopped" is the circuit opening relay.:;

I used the fuel tank/pump/sender/complete intake and wiring,computer sensors ect ect...

i am not certain what controls the firing of the injectors... maybe look on pirate or yotatech for some info on this?

interesting... if that is the only thing missing like you say then that must be the issue:eeek:

To my knowledge, that is the only thing missing. I have the C.O. relay hooked up, as-per the F.S.M., and still no injector fire. I only disconnected the plugs that I absoulutely had to, to get the engine out. I am positive that they are back where they go.
 
I really appreciate everyone's help. I'm not trying to be lazy and rely on everyone else to figure out my problem. I have been searching and researching everywhere I can find, going to hundreds of links that end in a dead end..... I am exhausted from looking everywhere, and all I keep coming up on now are the same things I have read dozens of times already. That link to the factory service manual helped ALOT:awesomework:
 
now that i think about it. i somewhat remember there being another circuit open relay around the steering column side of the dash... how long ago was this system up in running in another vehicle?

There is a "main relay" over there, and I have that hooked up too. The donor truck was running up to the day I pulled the motor out. About 10 days ago.:awesomework:
 
You could hook up your test light and grond E1 i think it is and it could give you an idea of whats going on. Im thinkin your missing a B+ wire on your ecu I just efi'd my truck last week and went through all this.

+B is hooked up. My main relay goes to it, as well as the ciruit opening relay. The factory service manual shows E1 as being a ground....
 
I remember there being 3 or 4 wires that had to be hooked up to power do you have a schematic for that year engine I cant find a fsm for that year

No, that's not me, but I have read that a couple times already:redneck:
and are you sure you're ignition splice is correct? doesnt it the signal from the igniton/dizzy?
Click to expand...
My ignition splice might not be correct. All I did there was hook my original coil wires to the new coil, and hook up my factory starter wire up to the new starter, so it will work off of my key.

I have a copy of an '88 specific FSM, but mine is an '89. I dont know if there is a difference or not....

i thought you might have already seen it.

do you have the ECU mounted? does IT have to be mounted/grounded?

im saving this thread...
my nephew is doing this very same thing right now. not sure how far along he is tho....not this far i dont think...

I usually have it bolted to a good grounded spot, just i case it has to be. I don't know for sure if it does or not. Maybe someone else knows. I will look it up:awesomework:

I plan on putting all the helpful information that I can possibly think of in this thread or a new one. I am mechanically inclined and all, but some of this stuff is overwhelming.

88 and 89 are two different birds...it may be that you've hookeded the original coils wires instead of the coil wires in the new harness...:awesomework:

88 and 89 are different. the ecm does not have to be grounded.

i would recheck your splices. something is hooked up incorrectly, if this thing was running fine 10 days ago

how much splicing did you do and to what did you splice? gauges/ignition ect... E1 is ground.

if you truck fires up when you spray into the intake then i would think that your coil and ignitor are hooked up properly.

I have the new one hooked up. It plugs right in to the efi harness, and the 22r coil doesn't. It has a different plug. Same as the distributor plug...they are so different, you cannot hook them up wrong. I attached the 22r coil wires to the front of the coil(-,+), where they were on the 22r coil.

That's what I was thinkin.:awesomework:

I am using the 22re harness ONLY for running the engine. I am using no other plugs, lights blinkers wipers gauges....none. The only real splicing I did was the ignition and the fuel pump. Everything else should be ran by the computer. Right??

this should be really close to your harness.

The only problem with that diagram, is that it doesn't match the donor truck. It shows the main EFI relay under the hood in the fuse box, and the ECM plugs are oriented different. On the '88 FSM, it shows the main EFI relay on the driver's side kick panel(where I found it), and the plugs for the ECM looked identical to the pictures shown in thier diagram. Not saying it is incorrect, but just going by looks, I would say the '88 FSM matched better......

Maybe there is an early '89 that shared the same setup as the '88's??? :eeek:


I checked the '88 diagrams against the '93 diagrams you linked to, and they do have suttle differences as far as what goes where.
