just a suggestion but have you tried a fault code reader to see if it has a record of the fault? the other thing that you should do that is not relevant to your problem is to replace the earth from the alternator to the block because this burns out due to the thickness of the cable and then the alternator has trouble pumping the amps to the battery.
Have checked the earth leads from the alternator to block and from gearbox to chassis as this was once a problem (months ago) with it not turning over..
the fuel pump relay i have is PN 90225811 (written on relay casing) and the relay is about 2" tall, when i got a new one from vaux the first one they brought out was a lot smaller with different pins on the bottom, the guy said this is the correct relay for an 89 astra GTE 16v
i'd taken the old relay with me so i handed it over and he looked the PN up and aparently this relay was for 91 onwards cars??
just wondering if anyone else with a 16v mk2 has the same relay?
ha ah. Whats and 91 gte?? Ive got a h plate 16v gte and its got the same relay as you have (6 pins on the bottom). I borrowed on from a mate and his only had 5 pins on the bottom?
Talking to a lad at work he says my problem is coming about due to the fuel pump pumping whilst the engine is being cranked. He says it should prime the system (position 2 on ingnition) and then not pump untill the engine starts. Mine does the above but also pumps under cranking so it is fludding the engine . I borrowed the correct relay and my car didnt start. This was befor i found out that it shouldn't pump whilst being cranked. I cant remember if it did pump whilst being cranked with this other relay.
Im gonna buy a NEW relay from vauxhall and see what happens.
we work together oddball?? We'll if we do, since you know alot more than me about gte's please could you come and fix mine?? Im still learning and that just what a electrictian that has had the same problem said.
The relay on my 89 16v has a gm code GM90 240 698. I have checked and my pump does not run with the ignition on. It only pumps when the engine is turned over. It continues to run while the engine is running and cuts out as soon as the engine stops.
It refers to this in the Haynes manual as a safety device should the car be in a heavy shunt and a fuel line be split. The fuel pump relay is switched from the ECU.I still think its the ignition module.
