well i have calmed down, and want to go wheeling this weekend so................
To answer some questions: First we have not checked timing, I thought it was computer controlled in a 91 yj FI? I also do not see how the timing could jump just because I RnR a fuel rail. I have a friend who was a GM electrical tech. He came over with all his gear (tech 2, test lights, super fancy voltmeter, etc) and we did a lot of tests. Here is what we found;
ALL relays, fuses, fuse connections, and wires running into EVERY plug/connection test good. We broke out the wiring schematic for the whole jeep. He traced things back and tested all of it via the schematic.
We checked spark: Spark at cap and at the plug. He used his fancy inline test kit for spark and the plugs are brand new as of 2 days ago.
I know we are getting gas because my fuel rail pressures up to 31psi with the switch to on, and you can smell gas when you try to start it.
Check engine light is now for some reason OFF with the key in ON! I have ZERO dash warning lights, just flat blank and the volt meter stays at ZERO with key ON.
So we checked the ignition wires and all test good. Now here is the FKed up thing: With the key in ON i can get fuel, it'll spark if we go to START and the starter cranks smooth (new started as of 3 weeks ago). Radio works, headlights/dome light etc all work. So after looking at the ECU "brain surgery" thread I decided I must have blown something because I tested the injectors via a power on unplugging. Plus I replaced them with the battery connected like a moron!
SO....... I have just replaced the capacitors in the ECU and I am waiting for the sillicon (100% silicon) to dry. I will update you guys once I install the ECU in about 3 hours.
Sorry for the hissy fit a few posts back. I just spent so much money on this since purchase doing upgrades and tune-up stuff (6 G's worth) and now that the engine is screwed I am understandably upset. Plus we had a big trip planned for tomorrow! keep ideas coming please, I will be in garage all night!
