Made an edit and added one. Not sure what the grey one is with two wires. If you can post what the wire colors I might be able to help you.

Anything that is on the engine should have a home. Look for what they could plug into. If you have not plugged in the ignitor the car will not get spark. It looks like you have a few items in there from the L that are no longer needed and need to come out of the engine compartment.

Does the CEL light up when you turn the key to acc.?

Sounds like you may be missing the diode.

azn0boi04 · 08-22-2008, 08:32 PM

CEL? whats that... when i turn the key to the ON position... the wipers work and the lights and stuff... but i dont hear the fuel pump, pumpin... u can usually hear a lil buzzing..

CEL= Check Engine Light

If the cel is not turning on, then your ecu/fuel pump won't turn on.

azn0boi04 · 08-26-2008, 08:30 PM

yeah my CEL is on.... along with the oil light...my fuel pump is still not pumping... my ECU has power to it....

bugeye-brawler · 08-28-2008, 11:58 AM

why wont the ecu work if the CEL is not on?

Sorry, i worded that poorly. If your CEL is not turning on then the ecu is not turning on.

azn0boi04 Are you positive the diode was wired in?

azn0boi04 · 08-28-2008, 02:43 PM

well i got it started... but a few bugs here and there..my CEL is one... but i think its cuz my O2 sensor isnt plugged in.... cuz i have to buy one....

my car stays on even with the key out...
my temp sensor doesnt work...
and i think my speed and RPMs... gas works tho =).
