740 stalling fix to pump/ignition relay

Post by Peter Coutts »

This item may help those in need...I have an 87 740 that has been experiencing periodic stalling while driving. Car has always started good. After sitting roadside for a few moments the car will start after turning over several times. I replaced plugs, wires and cap..still occurred.

The problem was found in the fuel pump/ignition computer relay found under the ashtray with the fuses. Upon taking out relay and removing the relay cover I found three suspect soldering points on the circuit board..they break down with age. I resoldered the points and replaced the relay and the car has not stalled since. Working great.

I purchased a new relay for $80.00 CDN and keep it in my glove box in case more solder joints breakdown when I am on the road.

I keep a spare relay. I bought mine for $20 us from www.fpcgroto.com the stealership wanted considerably more. Every 240, 740, 940 owner should have one.
