Hello and thanks for the great resource. A solution that works will merit a donation.
My Marquis had been sitting for about 3 weeks during a cold snap several weeks ago (Md.) And when I went to start it, it just tuned over. I replaced the bad battery which was 4 years old and suspected it was the TFI as I have had to replace that unit 3 times over the life of the vehichle which I bought in 88'.
I took the TFI to the auto parts store where I bought it for replacement if defective and the test came back ok on the unit and the guy said it could be either the mating unit in the distributor, the safety shutoff switch or I figure, the fuel pump. Is there a fuse for the fuel pump?
I know where and how to get to the fuel pump and test the line pressure, but I believe it's not running since I no longer "hear" it whining "running" when I turn the key to start, so I would like to start with the easier of the fixes before tackling the fuel pressure and tank if necessary, but am not sure where the switch is located or what it looks like?
There is something attached in the trunk near the driver side hinge that looks like a switch, but it appears to be depressed and fiddling with it has no effect on starting.
I've read the forum and will be doing the spark plug test for fire to the cylinders, but I need to locate that safety shutoff switch I've been reading and told about to test it for defectiveness. My Chilton's doesn't even mention it. :(
If that switch is it, great & thanks. If not, do you know where is it and is there anything else I should look at while troubleshootijng this out.
It's odd, the damned thing ran reliably, I parked it, it sait for 3 weeks during the freeze and now won't start.
Thanks for any help in solving this.
have the same problem?
