hey everyone, just letting u know i tried everything to get this 90 si crx to start, car started fine yesterday and ran perfect and filled the tank. and i was listening and no fuel prime, i switched out 8 good main relays and still nothing, also tried the fuse 14 i think the alt/sol fuse good i checked all FUSES UNDER DASH and UNDER THE HOOD nothing poped, the only thing i did today was install a flip out screen and that doesnt have nothing to do with the main relay or ecu or fusebox, like i said car worked fine befor this, i checked all grounds wires conections EVERYTHING im stomped, the car cranks just no prime of the fuel injections and i tried 8 relays and still nothing doenst even click, i held the Main relay and it feels like it vibrates for a min when i put the ing on, can SOMEONE PLEASE HELP ME ??? i want to drive my car.

 

Clearly you didn't try everything or your car would work now wouldn't it?

If it worked right before you installed your deck, then maybe it has something to do with that? Don't think that just because you think they are unrelated that they are. Go back to the way it was before you f'ed around with things and see if it works.

Also check your ground on the Tstat housing. Remove it and clean it up with some sandpaper and reinstall it.

 

check grounds, i had this problem with mine and it would run, then it wouldnt all of a sudden turn over. Definetly check wiring.

 

BUMP CHECKED ALL THIS, STILL NOTHING?? ANYONE ELSE PLEASE HELP ME RUNIN OUT IDEAS

 

quick way to tell if it's a fuel problem, try pulling your injectors out of your head while leaving them attatched to the fuel rail and have someone crank it for a second or two over a container of some sort. you'll either see fuel coming out or you won't. if no fuel comes out then take out your injectors and see if those are the problem. if no fuel still comes out then i would think it's the fuel pump since you have tried replacing the main relay.

 

BUMP, thanks for the info but anyone els? dont think thats the problem

 

Read the manual and jump the wires for the fuel pump. If you jump the wires and the fuel pump comes on relay again. If it doesnt prime jumping assume the pump just all of a sudden took a ****.

There is diagram that shows you which pins to jump to get it to prime.

(this is at the main relay also)

 

aight thanks. im going to try some things and ill let u guys know. thanks anymore idea's?

 

found the problem, it was the ecu p28.. put 12v wire to fuel pump primed and car would start, so i knew it wasnt the fuel pump, so i chcked relays nothing so i pulled out the ecu and even tho p06 obd1 isnt vtec i knew it would start the car and car primed and stared right up. so now i need a 0bd1 man p28 anyone have one for cheap lol. but thanks everyone for ur support.
