Car Will Not Start No Symtoms No Idea Need Help

[shaunpierre]

Car used to not start randomly after I bought it but would start eventually...., owner said coilpacks were getting hot.. So about a month ago on this hot day, the car would hardley idle, no power sputtering ect after driving for a while. it was absolute balls unless I let it sit for about 5 mins OFF. Then would start but problem would rrepeat every few kms. Coil packs were black as ash burnt out it seemed, so I put new yellow jackets and and new fuel pump and the coilpack loom from my gtr since the rb20 one was falling apart. And then the new fuel pump wass poping off the fuel filter..... Hose was shit around the edges. So after all this car is sweet started every time no stalls nothing drove nice skidded nice ect

Last week or so coming up to lights the revs will drop to about 500 and run stay there but not stall, when a/c is on its normal 850 ish,

Yesterday car died randomly at about 80km but it turned back on once I pulled overy and cranked it.

Drove to home and now won't start,

I have power

I dont have fuel getting pumped

It cranks but no combustion

I put the older pump in which works( connected it to power) but still nothin

I'm about to change o2 sensor

I'm also sus about the fuel pressure regs one has been changed its a nismo one with the bolt on the end.

I'm stuck Im usually fairly good with cars but this has got me f**ked, I've read some earths ect may be cause but all mine seem fine.

Any help would be much appreciated

O2 sensor has nothing to do with starting. Take off cas and turn by hand, with ignition on. check If coils are sparking, inectors clicking. fuel pump on etc

I have no power to the pump

Possibly be ignition module?

[Ben C34]

Could be heaps of things based on what you said. But no, not the ignition module.

could be your alarm

fixed.. after new pump, new relay, checking fuses ect. i found out it was a burnt out pin/wire in the boot. the plug looked perfectly fine but when i opened it up properly it had burnt it self apart from the pin or whateva so one wire wasnt sending a signal or power. this would explain sometimes starting sometime not.


such a fluke to find aswell. fml cars allright now. thanks for all your help and info guys. much appreciated.
