    if you get fuel and and a spark then its not getting any air ... try taking the filter off the carb and run it filter off i dont see whats wrong past air ot timing or the timing belt has slipped i think a saab uses and belt and not a chain time to let someone analyze it with the plug in to the ecu method more modern cars engage limp mode and this condition needs reset when its serviced

First you must check what the engine don t has...spark!? So if you replaced the cassette, you must check fuses and so on. If you don t see fuel pressure and you replaced the pump...fuses, control for the relay and power to the relay. Check injector pulse, engine compression is OK? Engine light is on with ignition on?! If not, check some others engine sensors have power...if not you must test ECM!?

Did you check for voltage at the coil pack low tension input
this comes from the electronic ignition and the distributer dc setting on a multimeter

check inside the distributer that the little magnet is still in place on the rotor and that the sensor is outputing pulses as it turns over
{you can use a meter set to AC range for this ...}
pull a plug out and place its metal to ground check for actual sparks
if this is there then its fuel ...

    iTS definately getting spark and fuel, it will crank and has a lot of compression, it started once and ran for about 15 minutes, then it died and hasn't restarted since then.

You require a code reader to pinpoint fault code.They are not expensive and easily obtainable, (E-Bay).Check wiring plug to coil pack connection first.

No Spark


Is the PCM controlling the coil's ? You have B+ voltage at the dark green with orange trace wire at the coil pack ? The other two wire's go to the PCM - the PCM has transistor's that supply a ground to those two wire's when signal from crank sensor is seen . Opens an closes to build up voltage an to release a spark . You can test this control with a test light . Video's on youtube.

No Spark


The relay for the fuel pump is working but have you checked that the pump is actually pressurising the system . Next you have power at the coil but is it getting to the spark plugs from the distributor.

Car stop running just cut off.could it be the starter.


No the starter has nothing to do with your car staying running you should check fuel issues fuel pump injectors regulators. Also most likely check ignition components spark plugs spark plug wires distributor cap and rotor or coil if equipped either or and check coil pick up sits underneth coil packs i would go to advanced auto parts and they can check coil pick up and coils or you can by pulling out spark plug and putting it back in wire set spark plug next to engine block if you see blue spark coil is good if orange bad not hot enough to ignite gasoline. is your check engine light on if so get codes read for free at autozone or advanced auto could also be crankshaft postion sensor or camshaft postion sensor lmk if it helps. if it helps please leave 4 star reviw and good comment thanks

My 1998 Buick Regal GS will not start. The battery is only one year old and the starter is turning. The wiring for the spark plugs was replaced 2 years ago. Is this a fuel pump problem? If so I would like...


If the motor is turning over, then the battery is good. You are either not getting spark or fuel.
If not spark, the crankshaft position sensor is usually faulty.
If no fuel, either fuel pump or fuel pump relay is bad, or clogged fuel filter, or fuel pressure regulator is faulty. You have a fuel rail that has your injectors attached to it. It should have a test port on it that looks like a tire valve. You can put a rag on top of it,, press it in and there should be lots of fuel pressure, If not, either filter is clogged or pump is not running either due to bad fuse or relay or pump is bad.
For spark, there is a crankshaft position sensor that screws in engine block next to the crank. Then from here the wires go to ignition module and coil packs, then to plugs and wires. You can test any relay or sensor with an ohmmeter in the ohm position. You can test any power in an electrical unit with a voltmeter

Engine misses, then shut off, won't start again


not sure about the 2008 model, but the earlier ones had coil pack problems. it looks like part of the rocker cover with around four torque screws holding it down and one multi plug at the end on the n/s of the engine. oh they used to blow the fuse at the same time for the engine management. 30amp dooor pillar/"A"post area. test by removing the coil pack, fitting the spark plugs into the plug outlets. earth the body of each plug and crank the engine, you shoukld see a spark, if not then there are other tests before confirming the coil pack. let me know how you get on.

Saab 95 1998 - wont start


The most common problem is the Direct ignition cassette, followed by the crankshaft position sensor. I am assuming that it cranks, but won't start.
