HELP! BH5 gtb not starting

[cuscogtb]

Was out driving lastnight when suddenly my car died on me..

Went around a corner a bit fast then suddenly the car stalled. Tried starting it back up but would not start, it starts to crank over and starts to fire then just dies ???. Luckily I was going down hill so push started it but couldn't accelerate at all, I mean accelerator pedal would be to the floor but it won't speed up, and when I push the clutch in it would stall again.

Plugged in the diagnostics and came up CEL 65 (differential pressure sensor) so called up Nick (Kamineko) around to help out. Swapped the AFM, Differential pressure sensor with Chris (MINTGTB) but still no go. Also disconnected the battery and no difference.

Been scratching our heads about this since lastnight and thinking it could be the fuel pump ???.

Any help on this would be greatly appriciated.

Also a big thanks to Kamineko for towing me back home lastnight in the rain! Will buy you some beers at some stage ;D.

most definately fuel pump... it probably fuel surged and shit the pump. ive had it happen about 3 times, not in subarus tho....

[kamineko]

weird one

fuel pump primes on ignition, sounds normal

prime it 3 or 4 times and makes no difference to start

afm tested good

all major underbonnet loom plugs are ok

ecu reports 65, differential pressure sensor - they will swap that later but i highly doubt the engine won't start because of that

maybe it is the fuel pump, unless the regulator isn't holding pressure

tried that this morning with no luck

[Guest boostcut]

are you getting pressure at the rails??? a fuel pump can flow fuel but if theres no pressure ie (shagged reg) it wont run..

although the pump could have really hand grenaded itself... what about a main efi fuse or similar? is the computer getting a solid earth/power

[Guest boostin]

They have a common fault where the diodes in the alternator reg fail, feeding a bit of AC through, and that interferes with the cam angle sensor output. Try unplugging the alternator and see if it starts.

[kamineko]

interesting

i didn't bother checking the cam/crank sensors because the engine was spluttering/popping while cranking

[Guest boostin]

Its a free easy test, so start with that.

[cuscogtb]

Will give that a go in tomorrow. Also going to borrow a fuel pump to see if it will make a difference.

that fuel pump got puled from car yesterday so should be sweet, come and grab it whenever.

[cuscogtb]

sweet cheers man. would you be able to give me a hand installing it? not too confident doing it myself..

[dubbedup]

yep peice of piss... i'll give ya a text after work,

[cuscogtb]

Tested the spark plugs and found...

No spark on number 3 but tested the coil pack and it works fine so must be the wiring ???.

Any ideas what could be causing this?

Any one had this problem before?

Tested fuel pump and working fine.

your leads stuffed? Dont take much and over time the rubber perishes. Same as an oven element where it earths itself and leaks the energy through the rubber. 8mm leads will help you.

got coil packs so no leads and 1 and 2 have sparks but not 3 and 4.

tried starting it with the alternator unplugged and still no go

[Guest boostin]

Checked fault codes?

[Guest keltik]

Are the big block connectors in the engine bay all clipped together nicely?

have checked the ones between the battery and washer bottle and are on properly

yup got cel 65 and swapped the pressure sensor with a good one but still no go

Next thing i'd try would be stealing MINTGTB's ecu when hes not looking
