Question
I have a 1987 Cadillac Allante that I have fuel pressure up to the injection lines, but the motor will not start and run because the fuelisnt getting into the motor. Is there a relay that controls this?

P.S. It starts and runs on starting fluid.

Thanks

Dan

Answer
Hi Dan,

NEVER use starting fluid on an aluminum gas engine. You could blow a cylinder head off or worse! Doing this type of testing you should put gasoline into a spray bottle. Staring fluid is only meant for diesel engines.

If you have the owner's manual it will tell you where each relay is located and what they are for. If you cannot find a fuel relay in the owner's manual I highly suggest you attempt t purchase the 1987 Cadillac factory manual from Craigs list or Ebay in order to diagnose and repair the problem. Th manual is required for many of the repairs o this car because few shops have information on your car.

I bought a 1987 Allante with 41k on it. I drove it until 65k and was one of the best and fun cars I ever owned in spite of having an ht 4100. I miss it.

Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
