Still not right - injectors only work for a second?

[DavidKent]

Is this right?

Car goes to fire then just won't run at all
Got the Injector rail out, they squirt for a second while turning over then nothing.

I can keep turning and turning and absolutely nothing happens

Car doesn't run and I'm supposed to be working at 5
Any ideas?

Sounds like a feul pump issue, does it prime on 2nd ign click?

[DavidKent]

Yeah primes fine
Started coming up last night with p0300 random misfire

It cleared this morning then came back again
Now it won't start at all

Tried crank sensors, pump primes and when I've tried and then pulled the fuel line off the rail there seems to be pressure there

[DavidKent]

Just took the line off, pump keeps going when I keep turning over, injectors don't - it seems to fire, actually starts for a split second

Throttle doesn't help at all

Check your getting a nice spark from the coilpack

[DavidKent]

Looks like a good spark - definitely fuel related in that case

[DavidKent]

Pump is working
Fuel is going back down the return

Seems injector related, tried 2 sets of injectors

Loom for injectors seems okay, visually fine

Where does it go next from there? Fuel relay?

What about the fpr mate?

[DavidKent]

If the return is working then surely the fpr will be? Wouldn't stop the injectors spraying?

[stevo67]

Surely though if the fpr wasn`t working correctly then the injectors would spray an insufficient amount or not spray at all?

[DavidKent]

I could see that if It were coming out the end - I've checked it since and nothing comes out of the vacuum side, might change it for peace of mind in a min, I've a spare anyway

[DavidKent]

Changed - not that!

[Pricklep]

Does it sound like this trying to start up? might be the same problem as me.

Thats unavailable mate, maybe we're not friends on there or some bullshit privacy thing

It literally starts, till the injectors stop running - Can only think it could be the relay under the ECU, unless its further related and is say, coolant temp sensor or something silly

[stevo67]

Do you have another fuel pump that you can try?It maybe low fuel pressure caused by a faulty pump.

[Pricklep]

Does it run for couple secs? mine did but wouldnt idle ect. Im guessing it squirts a little on 1, 2 and normal bang in 3, 4 then cutting out. I cleaned allllllllllllll sensors and so on. Ended up getting a dude out and it came with 2 logged faults on cylinder 1, 2 injectors.

Honestly save money and phone a diagnostics guy out because people on here will have you spending a fortune

[stevo67]

Tbh mate thats all we can do is suggest things,you`re right without diagnostics things could get expensive.

[DavidKent]

It doesn't run for that long at all - When i pulled the rail out and started it, it just squirts through all 4 injectors for one second, max - Then nothing.

Fuels coming out the supply pipe, and also going back through the return
Pump primes fine.

Had it on diagnostics machines before and stuff no problem, but i'm homebound now - Don't really have any money at all left which is pretty gay

Really can't see it being the pump, there's pressure in the rail, its been sat 2 hours, i just changed the FPR and there was still pressure there..

Tried another set of injectors too.

My cheap diagnostic machine still shows the original P0300 code though

[Pricklep]

Try and watch that vid. I bet it exactly the same.

[DavidKent]

It just comes up with some error - Probably because of privacy lol

It doesn't even start for 2 seconds, at all though - I'll get a video if needed, just means reconnecting battery lmao
