anyone know where the cheapest pumps are the cheapest i found were a little over 100$ without shipping (in hawaii almost nobody ships free)and i dont have that much to spend i just need some that work and fit anyone know???

So if you have a 1984 Euro they dont use this green wire that was mentioned? Im not getting spark now,but I did not long ago, and I dont believe Im getting any injector impulse, and my tach jumps around when cranking.....is this problem the flywheel speed sensor or the green wire?

928
 

try ebay, I bought mine pretty cheap....around $40

euro 928
 

My 928 sat for around 12 years and I just recently started working on it again. I had to have the ECU rebuilt and I replaced the fuel pump. The car started and I was able to take it out. Now the car just cranks and I dont get any spark at the plugs all the way back to the coils. both coils have power going to them, but nothing coming out. I also dont seem to be getting any impulse at the injectors....I have heard other people saying that its the speed sensor...I notice when I crank the car the tach jumps all over the place, is this a sign confirming this? Also where is this green wire people speak of......I have had that spark problem just recently but had injector signal now I have neither...please help.

i just ordered some pumps they should be here soon ill flush the tank out too i hope this will work
