95 z71 new fuel pump no fuel to injectors an no

I believe I have answered this at least twice already. The pick-up coil is what tells the ECU to fire the injectors. If the ECU is not getting the signal then either the pick-up coil is no good, not getting power, or not properly grounded. The same for the ECU....it must get power, the signal from the pick-up coil, and a ground.

Sounds like it could be the EGR Valve.If you can drive it and get up to 45-55 mph and it runs smooth then its the EGR valve that is stuck in the open position.I would take the EGR Valve off and clean the carbon out of it using a non-chlronated brake cleaner.

try swapping injector out of #3 cylinder. See if problem moves to another cylinder.

So your codes are: Multiple random plus misfires on 1,4,8. Misfire during startup, and ignition coil E (cyl 5) primary or secondary circuit malfunction.

You said that four new coils were installed. Perhaps the coil to spark plug order and the firing order have been scrambled. The spark plug wires may be old and leaky--especially if they are the originals from 2003. You could have a vacuum leak into the intake manifold, the EGR valve could be sticking open when it should be closed, the fuel filter could be clogged, the fuel pump pressure could be too low or stuck at the idle setting, the fuel injectors could be dirty, and cylinder compression could be low (putting on the wrong size o-rings when reinstalling injectors will prevent proper compression.)

I Would advise doing a compression test, make sure compression is even or within 10%. There could be a vacuum leak or EGR valve malfunction. The fuel injector could cause this as well.

Fuel pump is my diagnosis, or filter. I am a Ford technician.

If you do have fuel pressure, but there is no fuel getting into the cylinders to run the engine, then the engine does not have an injector signal or pulse to open the fuel injectors.

The ignition module and the pick-up coil/stator located inside of the distributor is what generates the signal that the ECM (Engine Control Module) uses to time and fire the fuel injectors, as well as the signal to run the fuel pump and the dwell signal timing to fire the ignition coil. A faulty ignition module can cause any one of these systems to malfunction.

That does sound like a malfunction with the ignition module inside of the distributor, and you can remove the ignition module and have it tested for free at most auto part stores. If the ignition module does test out alright then the problem could still be in the pick-up coil/stator, (it can be tested using an ohm meter by dis-connecting the wire connector from the pick-up coil/stator and the ohm reading between the two wires from the pick-up coil/stator should be between 500 and 1500 ohm's, and both of the wires from the pick-up coil/stator should show an open loop or an infinite reading between each wire and ground) and if the pick-up coil/stator is found to be faulty then replace the entire distributor, or the distributor will have to be dis-assembled to install a new pick-up coil/stator.

If you do purchase a new ignition module be sure that it does come with a silicone grease or a die-electric compound because it is a heat sink and the ignition module will burn up without it.

To install the new ignition module first clean out the mounting surface inside of the distributor. Then completely coat the metal contact surface under the ignition module with a thick coat the silicone grease or die-electric compound and do not leave any of the metal contact surface of the ignition module un-coated with the silicone grease or die-electric compound, and be very careful not to over-tighten the ignition module or it will be damaged.

As much money as you have spent, you could have fixed it and had a lot of beer money left. First thing to check is the KNOCK SENSOR. should be located near the starter.

Try some injector cleaner in the fuel--might be a problem in # 3 injector. One cylinder misfiring should not cause the engine to stall. Replace the fuel filter, and check the air filter. Does this engine employ a distributor or a coil-pack?
