Re: 740 1990 lags starting off/almost stalls
Problem solved! The fuel pump didn't have enough pressure. It was the right size pump, just wasn't a good pump. The pump was replaced and everything has been fine. I will say that through these posts I was able to track down and correct most of my problems. Thanks everyone.

Re: 740 1990 lags starting off/almost stalls
I will look into. I am going to check my fuel pressure at the rail as well. Could be the replacement pump isn't up to snuff.

Re: 740 1990 lags starting off/almost stalls
I cleaned the wire connections. The car now has moved on to revving 1500-2000rpm-just for asecond- when in neutral, and dropping to @750rpmwhen put into drive or reverse. I wonder if my timing is all screwed up. Everything happened after the fuel pump was replaced. Also I must note that the lagging ...

Re: 740 1990 lags starting off/almost stalls
I replaced the in-tank pump. My 740 has only the one pump. When I soldered the wires to the new pump I ran a continuity test and from top to bottom I no wavering. This of course doesn't mean that the continuity wasn't low to begin with. I will go back over the posts you mentioned. They were a great ...

740 1990 lags starting off/almost stalls
I have found so many great answers here. Many of you have helped me get my 740 running better. MY current problem is this. The car lags when starting from a complete start, or turning, as if the fuel is trying to catch up. Sometimes the car really pulses and bucks. I find that when I back off the ga...

Re: 740 1990 Heater fan won't turn on and fuse pops
Awesome, thanks. I have some of his posts. My 240 is a base model with the main pump in the tank. I found that out yesterday as I rolled around in my trunk and replaced the pump-the net was in really bad shape, cracked and brittle. So, new pump, net and BIG filter. I forgot how big the fuel filters ...

740 1990 Heater fan won't turn on and fuse pops
My fuse goes as soon as the fan knob is turned. I am wondering if there is something caught in the fan itself that could be causing this. I just cleaned out the air intake on the outside of the car, under the windshield, but haven't pulled the guts out yet. I am currently hoping that a new fuel pump...
