New rebuild, injectors not firing s4
 

OK I recently rebuilt my TII myspelf. Motor has GREAT compression. However the thing will NOT start! I figured out, that ive got spark, and I checked and the fuel pump is running, which means the Computer is working since its getting the signal from the AFM.

Anyway, so i pulled the spark plugs out and cranked it over and NO FUEL! interesting. Now during the rebuild, I installed NEW injector clips, and I removed all emissions.

Anyway so my concerns are as follows. I know of nowhere where I can get a conline copy of the wiring diagram, that contains the injector wiring for the car WITH the resistor pack Could anybody point me in the right direction?

Also can anybody tell me what resistance I should be seeing between the ECU pin for the injectors and ground?

have you made sure you have all the connections under the dash connected?? I did what you did and wasnt getting fuel. It ended up being that I forgot to plug in a part of the wiring harness that actually didnt connect to the Ecu but instead to something mounted under the dash. One of the big semi clear orange harnesses

Did you hold the injectors against the intake manifold while you were testing them? They may not be getting grounded well enough from the harness. This is rather moot though because they if they are not firing because of bad grounds it is either the main harness ground or the extra, thin gauge, ground running from the UIM to the middle-ish of the firewall, one or both are either not hooked up or corroded badly. Make sure you check these. And just for shits and giggles, have a friend hold a somewhat heavy gauge wire on the negative terminal on the battery to somewhere on the block (somewhere safe for his arm) or just hook it up to a bolt as a temporary measure, just to see if this is the problem.

i think you probably miss a ground somewere. check the ground on top of the engine make sure they are good and make sure you have a good ground from the engine to the chassis too

o man, ground is a bitch. i incorrectly grounded one of mine and i cant read the oil pressure!

My '7 just suffered from a failed resistor pack. Each resistor is marked at 6 ohms, mine measured in at 5.2 ohms each except for the failed one (infinate.) I would think that adding 5-6ohms over the normal resistance would be the norm for 86-87.5 cars.
