Not sure if you have a 1996 Cadillac Seville or a 1998 Olds Aurora but I would check the Ignition Coil Packs. One or more of them may need to be replaced. Also if you were working on the car and got the wires plugged onto the wrong coils then the firing order sequence would not be correct and this can cause a misfire or backfire conditon.

Ignition wires cannot rest near the primary wire harness of the ignition module, which can cause electrical interference and a no start condition or a misfire condition

On my friends 1997 Cadillac Seville it was easy to replace all 4 coil packs took less than 30 minutes and made the car run much better. Just make sure to get the firing order right. If necessary find a diagram of the correct firing order for you vehicle.

A good place for mail order auto parts is rockauto.com

I have pasted a picture below of what an ignition coil pack looks like

Why did engine running, won't restart.


lots and lots of reasons, guessing. over 50 (bad engine?)
but does it crank?, no car starts unless it's cranked or
like my car, push started or gravity started (a 6sp m/t)
if engine fails to start , and cranks robustly (fast starter motor)
then
1: never tuned up, running 10 year old spark parts.
2: blow fuse. check fuses.
3:; lost spark, check spark.
4: flooding or loss of fueling. to unflood any engine, crank at wideopen throttle (oper, guide tells you that)
5: timing belt not changed at 60,000 miles it will fail, and will not start
or start have like 1/4 power.
6: lost compression in or more cylinders.?

or
get it serviced? if all that is too much work? or confusing.

Car non start maybe cold battery


There are several things that few people know about starting cars in cold weather. 1. Check your battery to make sure it is not rusted, leaking, and has a charge 2. Jump start your battery with another car, even if you believe the battery is good, this often times will still start your car. 3. If your engine is cold, and you have an older car, ensure to get your fuel lines to the engine flushed or have fuel injection service performed 4. The engine tends to warp the same way wood does during the extreme cold, do not be afraid to continue trying to warm up the engine by constant cranks with it is cold out. Your not going to hurt the car, the worse that could happen is too much fuel will enter the carborator and cause flooding in the system to occur. Wait 20 minutes if this happens and start to crank again 5. Bad spark plugs are a major reason why many cars take a very long time to start 6. Please have your spark plugs removed and exchanged for new ones. Over time, spark plugs become fowled and prevent the car from starting even thou you hear cranking!!

check if got a spark , pull off HT lead wire hold it 6 mm from coil or ground, crank engine if good spark is present during cranking, then check your fuel pump, if not check ig. coil and amplifier. first see timing belt make sure it is turning with engine cranking.
