View Full Version : Car Wont Start.........

06-07-2008, 11:35 PM
Recently picked up my project 318ic cabi and it was running fine and started with no problem....

The other day i started it and it was running(idling) for about 15-20 min and the engine started to shake and shut off. After this happened no matter what i did it wouldnt start. It cranks and the engine wants to start but wont......

Stuff i checked or did:

Intake hose
new air filter
new spark plugs

I have no idea what it could be or what it is.

I also would like to know if anyone here knows or has a diagram of the fuse box with all the fuses and what amp fuses and where they go.Mine is missing like 7 and i have no clue what amp fuse to put in.

Any help is appreciated.

First of all you have to establish what the main cause is; no fuel/no spark. If both are present (more unlikely), you have to check main mechanical problems such as timing, compression etc...

The fuse box has many spear fuse spots that are empty, so that wont be a problem, but you do have to check wich ones. I might have a spear owners manual for it...

did you check your fuel pump???

sounds like you ran out of gas. i'd check that first.

Gas was the fist problem i thaught of but i put in gas and still did not start.

As for the fuse box,i tested the empty location and they had power coming in to them so i'm thinking it has to be for something....

How would i check the fuel pump....i took out my back seat and took the little cover off but how do i test it to see if it still works?

Could this also be a relay problem or any other electrical problem?

you'll hear the fuel pump if you turn the key to 'on' - it should make a humming sound.

what do you mean 'wants' to start?

here's the fuse box numbers for you. link (http://www.r3vlimited.com/board/showthread.php?t=60297&highlight=e30+fuse+box)

^^^Thanks furyriderx after i spoke to u on the fone i went and checked those 3 relays and i played around with them and figured out that it was the fuel pump relay. I switched it and vrooom right there it started.

Thanks to all for their support and input.
