Hi:

I went to retrieve my always reliable 1990 760ti summer occasional driver from winter storage today where it has been for 5 months. It was stored in a heated warehouse, clean, cement floor - winter home to a number of collector vehicles (all of which apparently started and ran smartly when their owners retrieved them!...).

Before I put it into storage I topped up fuel, put in stabilizer and removed the battery. I put the freshly charged battery in this morning and it cranks strongly but will not fire. Does not smell like flooding, and all else looks good in engine bay, no fuel leaks etc. No drips or other oddities underneath.

I have never had any kind of no starting issue with the car. In the past when I've stored it in our unheated garage at home for the winter I have to recharge the battery from time to time, but it has always fired right up with a fresh charge.

I would appreciate ideas on narrowing down what the likely culprit might be. I was not able to pull any codes in the time I had today, and I did not have my code-pulling/resetting cheat sheet with me. Would much prefer to get it running and out of the warehouse it it could be something simple(?)rather than have to arrange towing back home to trouble-shoot/fix.

Thanks all.

I would start with the usual suspects of fuel injection relay and radio suppression relay.

Thanks for your insight Randy. I went with the fuel pump relay as suspect #1...and just got back from successfully getting it going with a new relay!!

I love it when things are simple. For the reference of anyone in a similar situation. The correct relay for mine was OEM part # 1392914. It has a green cover and white plug base. The (bad) one I removed is stamped with the word "Volvo", the part number on the top, 89 8473, 12v and Made in Germany.

The panel that you have to remove to access the relay array is held in place by 3 Torx screws, 1 plastic slotted-head trim plug, and two clip-in fittings on the leading edge of the vertical portion of the console panel. When you remove the Torx screws and the plastic trim plug it should pop out at the leading edge quite easily.

Case closed for this issue....
