'88 740 won't start.

[Earl]

Split from "'89 740 B230F (USA Spec) won't start

Found some Ether and did the 5 second squirt. Bingo - it ran for a second or two and stopped. I tried a few times to make sure it wasn't a fluke and each time - same result.
So, having established it's a fuel problem (despite what a "mechanic" here told me that it was definitely electric) and having replaced the fuel pump relay, any pointers?
I imagine the fault code towards the throttle switch might be a candidate? Can I do anything in a progressive manner, I.E. from the tank pump forwards to eliminate the possible causes?
Now I have eliminated 50% of the suspects, that is: anything electric, I am feeling a lot more optimistic.
Again, my thanks all round.

Mines an 88 model and have the same problems . I've done replaced both fuel pumps and filters , the radio suppressor relay (operates the injectors)..all that after putting in a new ECU . I get fuel all the way to the fuel rail , but injectors will not open....... I'll be following this thread like a hawk .

Earl,

I split this from the other topic because the cars are different in how the diagnosis is done. This would then give owners of the older model a chance to answer your particular problem.

However, I have now found that you have posted the question yourself so I am going to lock this one so all the answers go to the other post.

Who would be a moderator??

Bill.
