Hi again Seems I've always got something wrong with this car. I had some problems previously which we solved by getting a new alternator for the faulty one I'd bought and changing out the engine temperature sensor. A couple of days ago I filled the car with petrol drove the 4 miles to work and left it. On my return it tried to start, was nearly, then died. I then killed the battery by cranking it with no success. Yesterday I called a breakdown service who suggested I remove the fuse for the fuel pump, which I did, the car then ran until all the fuel had been used and as expected died. On replacing the fuse the car would not start again and had to be towed home. Today I've removed the plugs to find them totally dripping in petrol. Has anyone any idea why the car is overfuelling and what can I do about it? My car is an 88 2.8 injection. The fuses I pulled were labelled F/P INJ2, INJ1 and F/P -FAN-CH. Were these the ones to pull? I'm stuck again guys and girls. Sadly I have no Chevy guys round me as I'm in the North od Scotland, wise career choice eh?? Thanks in advance Steve

hi, id look at my codes first see what they give. could be many things but that should give a clue, knackered injectors though id be suprised if they all went at the same time so dodgy injector wiring or bust ecu not opening the injectors right???? dodgy fuel pressure regulator overfuelling or maybe theres a sensor out telling the ecu to over fuel, like map/maf etc.
get the codes.

Your 2.8L fires it's injectors in two "batches" - essentially, the computer is "ground control" which means that the computer completes the circuit by connecting the circuit to ground. The fuses labeled inj1 and inj2 are the "hot" side of the circuit and these protect the wiring to each of the two fuel injection circuits (remember, fuses don't protect the equipment in the circuit, they merely protect the wires from turning into heating elements due to excessive current). Pulling the inj1 and 2 fuses will prevent the car from starting. The third fuse is for the fuel pump. Apparently, the garage felt that the fuel pressure at the rail was excessive. Excessive pressure can cause hard starting due to overfueling. Check the pressure on the rail using the schrader valve - if it is way out of spec, the pressure regulator may have gone.
