Still having problems with the XE corsa, Dad thinks it is Fuel starvation.

So far we have changed:

Fuel Pump Relay
Air Flow Meter
Coolant Temp Sensor
Throttle Position Sensor
Distributor and housing
HT Leads
Fuel filter
Dizzy Cap
Plugs

None have changed it really, it struggles under load and judders all over the place.

This is what is happening from idle.

This is foot down to rev it up.

But driving along it does this when you are barely holding the throttle

I've check all around the rail and it isn't leaking and everything seems well connected

Is it a recent conversion car? What pump has it got in it? SPI or MPI?

I would say check fuel pump or fuel filter, not really sure what else it could be dude. Unless maybe a dodgy lambda sensor?

It's been running for a year or two now with no problems, it's got the 1.6 pump on it.

Fuel filter has been changed, Dave gave me a pump to try tonight. It doesn't have a Lambda sensor.

Got the FPR and fuel rail left to check as well if not then it's injectors etc.

Fairly certain it isn't a sensor causing the problem and more like a blocked pipe etc.

Sure plastic casing hasn't come unclipped from injectors, or wiring going to that casing?

I've taken it off and put it back on several times now so pretty sure.

Wiring to the casing across the top of the injectors right? If so yes that all has been checked

you sure it hasnt got a lambda sensor? ive not heard of an electronic fuel injected petrol engine that doesnt have one before? check all your fuel lines are clear, just undo both ends and blow through. is the fpr the same as a zlet on yours? common to lots of vauxhall engines. i have a brand new one unused you can have. fits z20leh, z20let, x20xev & xer pretty sure its same as z14xe and x16xe to.

100% it doesn't have a lambda, the early XE's didn't have them.

I think it will fit but its different pressure to the XE from memory?

I'd look at the fuel pump or swap the ECU if you have a spare just to try it.

Mine did that once when water ran down the inside of the loom and stopped inside the ECU.

Wouldn't really use GM plugs after seeing my neighbours coupe turbo eat 1 and he said it's not the first vauxhall he has had that has ate a GM plug.not that i would fix your problem Darryl but maybe worth changing for some better plugs.

I've always used them and not had a problem but thanks for the heads up.

Fuel pump changed this evening and no change.

Taken the Fuel rail and FPR off.

Any way of checking the FPR is ok?
