Have you checked for power going into the coil?

Check for power at the center wire on the coil pack plug. You should be getting 12 volts, if not replace your ASD relay.

The ASD Relay provides power for the coil and other essential circuits. This relay is activated only for a couple of seconds when the key is first turned on and remains on as long as the car's computer receives a crank signal. The ASD Relay will not activate without a crank signal, and that could indicate a bad crank position sensor or if the timing belt is signifigantly off.

Also check the ignition switch at the ignition tumbler in the steering column. If the ignition wires do not show 12 volts at the RUN position of the key, then there is a problem in the wiring.

Hope this helps. Please do rate this answer. Many Thanks.

Symtons of coil pak or car wont start after warming up

Most likely a failed crankshaft/camshaft position sensor. This will not set a code if the engine is not starting. One way to check it out is with a spark tester - an inexpensive tool. Have an assistant try to start the car warm while it is installed and check for a pulsing light. If none, there is no spark. Some helpful links - and

I have a 1988 volvo 740 turbo with no spark. I tested the coil and it is good. with key on I am getting oscillating power. Also when the ignition is just turned to on and not cranked I can hear two...

check the crankshaft postioning sensor. this should be located at the rear of the engine where the tranny and engine mount. if its bad it will not let the coil put out spark. I had the same problem with my 940 and that solved my problem. try this, gently pull up on the sensor cable, then try to start the car. sometimes it will start, but if the sensor is completely gone, replace it.

I have an oil leak between the rear of the engine and the transmission bell housing what parts do i need and how can i get a repair manuel

Unless it's coming from the valve cover down, this is the rear main seal. Generally, you'll have to remove the starter, axle(s), linkage & transaxle, then the flywheel to expose the seal. It is mounted in an aluminum bracket that bolts to the engine around the crankshaft to hold the bearing and help to provide the proper sealing to that area. While you are there, you should consider replacing any seal in that area to prevent the need of pulling the trans again.

If you do that, you'll remove the entire bracket & be able to easily remove the rear main seal.

The seal can also be pulled out where it is if you are careful, by using a couple of sharp screws & tapping into the center of the seal, away from either edge so as not to damage the housing or the crankshaft, then pulling the seal out. I use 2 screws as a rule & predrill with a low speed drill making sure not to touch anything but the center of the "hard" area between the 2 surfaces. A bent tip on a screwdriver can also provide you with a means to pull the seal. Either works, you just have to be sure not to scratch the crank or the aluminum bracket that holds the seal.

This method eliminates the need for replacing other gaskets in that area.

Parts: Rear Main Seal (set) includes the paper seal. Consider the Trans main/input seal, you are there and the method for replacing it is very similar, pop it out & push another back in. You'll need RTV for the paper seal if you do replace it.

As far as the manual, there's more than one type & place to get them, including on-line. If you go to one of the parts stores like Autozone, they will provide you access online to vehicle specific repair info if you just take a minute to register. Pep--boys has a multitude of manuals for most vehicles.

good luck.

No spark, 1988 Toyota Camry 3SFE 4cyl, 5 speed.

there is no crank sensor on this vehicles 2.0L. If you have power to the coil, new coil, cap and rotor try this if not done yet>>>Unplug coil power first....Try pulling off the distributor cap, and make sure the rotor is spinning with the cam...If this fails to spin, inspect the entire distributor assembly. If it passes, Inspect all the power circuit and wiring to the dist assembly, if ok possible ecu. i recommend having a mechanic check it out!! Hopefully this helps...please rate...thanks

Motor swap

If your planing on swaping the 2.0 non-turbo(420a) to the 2.0 turbo(4g63t) your problem will be that the motor and transmission are on opposite side of one another. My GST has the trans on the passenger side and the motor on the driver. The 420a is just the opposite. If your serious about it you should get the motor rebuilt with higher performance crank, pistons, rods, exc.  And they make turbo kits for the 420a.  But you'll need better fuel delivery and some mild tuning.

1998 Mitsubishi Eclipse 2.0 non-turbo DOHC engine vin y. Car stalled and turns over but will not start. Towed to repair shop and at first they said it was a defective cam or crank sensor, but now they say...

don't get the "Cardone ECC model 793013" . i just check it out and when you click on the " See all vehicles this product fits " link, it shows this:
5fcbf9f.jpg ------------------------------------------------------------------

the problem with it is that the '97 PCM will not work on a '98. the pinouts on them are slightly different. The only 2 years that are interchangable are the 98 and 99 year models.
The part number for the correct one is 5293190AC.

If you get a remanned PCM that needs progamming, anyone or any shop with the correct programming tool can do it.


1995~1999 Mitsubishi Eclipse RS & GS with 2.0L non-turbo engine (Chrysler 420A engine) ECUs have been equipped with reprogrammable processors since 1995.
To reprogram Mitsubishi vehicles, you must use one of two different reprogramming tools. For the 1995~1999 Mitsubishi Eclipse RS & GS (with Chrysler 420A engine), you must use a Chrysler Flash Reprogramming Unit, MIT992000-A . Click here to order one from SPX, or call them at 1-800-533-5338.

I would suggest just buying a used (98 or 99)PCM. Then all you have to do is unplug the old one, take out 3 bolts to remove the bracket/PCM, pull it out, 3more bolts to remove the ecu from the bracket and bolt the new one in place. Its about a 5 min. job.
