    Error codes 185, 186, 187...?

    I tested every sensor in the engine, there was some rhyme and reason to the order. The first time I tested the fuel pressure it was fine but the car was also running fine (no codes). I then listened to the injectors with a mechanics stethoscope, they were all opening fine. I changed the FPR...

    Error codes 185, 186, 187...?

    if anyone is wondering, it was the fuel pump that I just changed 2 months ago.

    Error codes 185, 186, 187...?

    It again died and would not start. After trying to start it a few times, I disconnected the vacuum line to the FPR and it started right up. So, I changed the FPR. It is running a lot smoother but it still wants to die/bogs down at WOT. For now I think I can limp it home, when I get there I will...

    Error codes 185, 186, 187...?

    so the pressure is good at the rail, I checked the injectors with a mechanics stethoscope and could hear them opening. for what ever reason (I didn't change anything) it is running fine now. Did a KOER test and came up with no codes. The only issue I notice now is that it is sluggish at WOT. One...

    Error codes 185, 186, 187...?

    so I'm pretty sure I have narrowed it down to something with the injectors. I'm getting more than enough fuel to the rail, just not getting any fuel through the injectors.

    Error codes 185, 186, 187...?

    I saw somewhere on here that you can test to see if your fuel pressure regulator is working by disconnecting the vacuum line. I did this and I finally got it to start, I kept my finger over the vacuum line to make sure it was running with correct vacuum. Does this mean me FPR needs to be replaced?

    no vacuum leaks. it is a fuel problem, I sprayed some either in the air cleaner and it started, up ran until I didn't spray any either anymore. I disconnected the fuel line and ran the fuel pump fuel came out (not very fast though) I don't have the right fitting to connect my fuel pressure gauge...

    Error codes 185, 186, 187...?

    Yes these codes are KOEO. I can not get it to start so I can not get any KOER. I reset the codes and it passed (111). Tomorrow morning I will check for vacuum leaks and fuel pressure. Will post in the morning...

    Error codes 185, 186, 187...?

    I've searched all over the place and found a couple of people that have had the same codes pop up but none of them post what the fix was. As of right now the P.O.S. won't start, it sounds like it really really wants to. The car is a 92 explorer 2wd 4.0L auto. A few months ago I replaced the fuel...

    Fuel Pump only getting 6.4 volts

    don't know why but the fuel pump is working now. WTF?! The only thing that has changed is the ambient temp, and I changed the PCM earlier today but I tested it and tried to start it and it didn't work! Yes I have tested both and it is the same at both. Although, I did not even think to check...

    Fuel Pump only getting 6.4 volts

    Thanks. Checked both, as far as I understand if the PCM was not working the check engine light would not come on, which it does. the fuel pump relay will click on and off when I connect a jumper to the FP terminal at the VIP test connector. Out of curiosity, I know the green relay is for the...

    Fuel Pump only getting 6.4 volts

    So like it says my fuel pump is not working because it is only getting half of battery voltage. I have searched all over the posts here and have not found anyone to have the same problem. Lets start with the basics; The battery voltage is 12.5 (at chassis Ground), The voltage at fuel pump is...
