i have a vauxhall astra 1.4 single point injection 1997 it runs butifly but forme time to time it cuts out and won start iv had a frend out and he has told me the igition side of it is 100% he tells me that the injector is not opening to let fule in the the engine

he says the ingector is fine and the fule presher is good but it seems to the ecu is not telling the injector to open he says that it might be the cranck sensor but he carnt seem to locate it if anyone can shed some light on it it would be a grate help

there is a spark at the right time
there is fule presher
the injector works fine
but no signel gets to the ingector

some info in to this prob would be grate

btw its been on the computer and has no cods stored or pending so it looks like im going to have to go old scholl diagostics so can ayone tell me where the crak sensor is as i carnt seem to locate it to test it and does the amplfier have anything to do with the fule injection

Have you had the fault codes read if not you can do it yourself-Warning you do this at your own risk How to Read fault codes on early vauxhalls

there are no pending or stored fult codes logged

Sorry just spotted you said that in your first post whoops:) from memory the crank sensor is located near the crankshaft pulley at the front of the engine and on later vauxhalls it is at the back of the engine block in the middle-you can only see it from underneath-but I,m not sure when the location changed.

Here is a picture of the one that will help identify what it looks like it is the black component with the multiplug

ok iv had the cranck sensor out and it is working 100% so i replased it anyway and traked the wiering all the way back to the ecu an the wiering sees ok but the prblem is still there

i have put a ht tester on a plug and emooved the air filter housing o i can see the injector in the thotal boddy when i turn it over there is a spark but no fule (the ijector is ot pening) so i put a node on the injector and no signal is getting to the injector

there are still no trubel codes pendin or stored on the ecu
