Fuel + Spark but not firing?! - Drifting forum

topi · 06-08-2008, 20:23

Help needed. (SR20)

My car was running mint, and then it was left of my drive for a week. Went to move it... fired up and died..

I've got fuel (put an extra jerry can in incase), which is getting to the plugs. Each plug is sparking. So what the hell else could it be?

Have you flooded it? Whip out the fuel pump fuse and try firing it up again, then refit it while it's running.

topi · 06-08-2008, 20:32

I thought it might be flooded, so I took the plugs out and blowtorched the bores after leaving them 5 mins, cranked the engine over a couple times without the pump fuse - and reassembled. It did attempt to run when I put them back in.. but then died again.

When you turn it over, you can feel a slight BWOP from the exhaust, like its trying

You got compression? Blocked intake, try taking the intercooler pipe off the throttle body, crank it over whilst spraying brake cleaner in there (watch out for backfire) if it coughs or changes note then you know the inlet isn't blocked

Well I just took the pump fuse out and tried starting it like you said Mitch, and it did fire up for a little while.

Put the fuse back in, tried it and nothing. You can hear the Walbro whiring, but it's almost like it's flooding the engine?

alex_200sx · 06-08-2008, 21:00

Ooh, i remember now, i had this with my CA18 (i know you've got a SR) but the injector wiring had shorted out and was permenantly spraying fuel into the bore, it did start but misfired, worth a shot. Is there any one plug that's wetter than the others?

2_stroke · 06-08-2008, 21:02

i know exactly what it is.....

....theres a midget stuck in there, he must have crawled up ur exhayst at night and that might be the coughing noise try a pack of lockets lol

topi · 06-08-2008, 21:05

Shut up Eddy lol.

Alex - all the plugs seemed equally wet :S argh

alex_200sx · 06-08-2008, 21:11

Bugger, there goes my theory. I would personally try a compression test next. Cant think of anything else coz my brains gone to sleep, buy me a red bull and we might get it sorted lol

topi · 06-08-2008, 21:17

Fuel pressure regulator maybe? How can I check?

topi · 06-08-2008, 21:48

Sorted!

I re-red your advice Mitch, and put the fuse back in WHILE it was running. Stuttured a bit and them BWARP sorted!

Cheers for the assist

2_stroke · 06-08-2008, 21:51

Nice one

You still still wanting the beads blastingness tomorrow mate?

topi · 06-08-2008, 22:37

Possibly dude, I've got a feeling I might be able to aerosol them on actually, as it's a slightly wider tyre this time.

I'll take them to work and have a go at lunch time, as it's a little late now ha.
