If the NOID lamps fail x6 (no injection pulses)
then the ASD relay is dropping out)
87 is the really really old RENIX/Benicx injection system. on 4L
i had a 88. same car.
see for permissive to inject.

on my old I6 4L Renix sys
the injectors are all grounded , that is correct
and the ECU drives this hot switched ! unlike most cars.

Replace fuel injector cadillac cts 3.6

First off..Do you have the High Pressure direct injection 3.6 LLT engine or basic 3.6 Engine ? Yes the upper Plenium has to come off, but you will have to probably pull your wipers off, and the 7mm screws that hold the cowl beauty panel on and then there is enough cleareance to remove the plenium, disconnect throttle body snorkel tube at throttle body, remove 10mm bolt at brkt drivers side of throttlebody (ball stud) if I remember right, then there are 13mm bolts at back besides the obvious ones you can see and carefully lift it up off engine, thenyou can get to rails for the injectors, to bleed off 3.6 low pressure fuel system pull fuel pump fuse in trunk fuse box and start it let it run out of gas, then bleed Schrader valve too on rail, if you have a high pressure direct injection llt engine let me know, will describe procedure to you

Getting good fuel pressure to carb but no fuel to injecters can a bad relay cause it to do that

No, but wrong thinking can get you a lot of scathing responses from crabby old mechanics. lol, like me! If you're getting good fuel pressure to, to the "throttle body injection" unit, (it only looks like a carburetor on the outside-it has about 120 fewer pieces inside it. And any form of fuel injection threw carbs into the fossil pile they deserved.) you are getting fuel to the injectors if you have fuel pressure in the line.
Have you watched for fuel spray out the bottom of injectors while the car was being cranked over? If so, and you have no fuel coming out, then you need to check the injector circuit. It is a fused circuit, so check first for the injector fuse. There should be an underhood fuse and relay block, so check there. Power for the injectors should be available at the injectors anytime the key is on.
Post back if you need more help. I was only kidding in my first response, cheers.

I have a 1998 chevy express van.i have spark and fuel up to the trader valve.the van is not getting gas to start.i am thinking it is the fuel regulator module or the fuel regulater. what do you think?

Put a fuel pressure cage on the Schrader valve to test for fuel pressure. The fuel pump may not be running up to snuff or the regulator may be faulty. The strainer sock on the pickup tube in the fuel tank may have collapsed which will restrict the fuel flow.

Getting fuel to throttle body, but, car will not start. Fuel injected system. Injecters are not firing. Starts when gas is poured in throttle body then dies. What's my problem?

Sometimes there is a fuse just for the injectors if none of the injectors are firing id check the fuse.
But first check to see if the fuel injectors click because if they do click it could be the fuel pump.
Are you able to figure out what the fuel pressre is at when you prime the system? You can do this by checking the schrader valve on the fuel rail by plugging in a gauge and see if it has pressure when you turn the key.
if the injectors dont click and you have fuel pressure check the fuse for the fuel injector system (depending on model fuel injector system.) Cause you need to first make sure the fuel injectors arent firing cause it may be a pressure regulator problem or a fuel pump.
if you need further assistance or have a question about anything ive said please follow up with a comment and i will be glad to assist you further from there. Thanks and good luck.

Fuel injecter fuse blow imeditaly when ignition turn on

sounds like a short in the wiring from the fuse and the fuel injector junction block. GM like most fuel injection systems control injector firing by the computer providing ground to each injector in pairs or individually. The fuel injector fuse provides power to the injectors using splices therefore enabling one wire to feed 6 injectors. A shorted wire at any of these wires will blow the fuse. On one rare incident I found a faulty computer caused the fuse to blow. A shorted injector will just cause a rough running problem due to the injector stuck either open or closed.

1.5 diesel megane injection fault

The cheapest way to go is to change the fuel filters first and the air filter. Then I would change the crankshaft sensor.

You may have to bit the bullet , and have the fuel pump changed before the fuel injection pump. The fuel pump in the tank can be loosing pressure to the fuel injectoin pump.
I think the lesser cost is the fuel tank pump vs. the fuel injection pump.

The system runs of fuel and air. No spark like on a gas engine.

So the problem can only be lack of fuel or lack of air getting into the vehicle air induction. A restriction in fuel or air will make the engine run poorly.

Check to see if the 15 amp EFI fuse is blown.
This fuse controls the ECU and the injection.
