Car Died. Diagnosis?

[adamisbomb]

my father in law just decided to take it to a shop. i should know next week whats up, hope its nothing horribly expensive. it now has brand new ignition coil, spark plugs, fuel pump, fuel filter on it. and yes it wont start still. oh well. i hope they find something simple like a relay or something. i hope the whole motor isnt gone.

Great thread and Bill's Adivce is great. The Female recepticle for the Fuel Pump Relay always has 12vdc to terminal 30, even with eng off, key out of ignition. Closing the circuit between terminal 30 and 87 sends 12vdc to the 15amp Fuse 23 and on to the fuel pump. I cannot get 12vdc to the fuse and so there is a break in the Green/Violet wire somewhere between Terminal 87 of the relay and Fuse 23. Any idea how I can turn this wiring nightmare into a sweet dream? By the way, the Fuel pump does work. I supplied 12vdc from a known 12vdc + source directly to the outbound side of fuse 23 and could hear the pump. So, wireing is good between Fuse and Pump but not fuse and relay.

89 535... Had the same problem... car stumbled to a stop like it was out of gas... Would crank and crank it but wouldn't ever start... Changed out the fuel pump from my other car but never helped... Jumped the fuel pump relay but nothing... put in a fuel pump relay from my other car and it didn't help... but I was so close... Turned out that both the Main and the Fuel Pump Relay blew

wow this forum rocks... I have the exactly the same issue.

Try disconnecting and recharging the battery until charged then I bet the car will start.

You have the same problem as me where the alternator is not charging the battery enough.

Oh yes it will turn over and all the electrics work fine but it seams the computers onboard will not work under a certain volatge thus fule pump etc not working correctly.

I had the rough idle which became more regular and then no start.

Good Luck

So your problem is alternator, not a fuel pump. I am confused trying to read and learn from this tread.

Adam, any update after having the ship check it?
