Please Help 7mgte Wont Start

btwilson86 · 12-01-2008, 07:41 PM

Well, on my N/A I had a similar problem. Ignition timing was off (Distributor 180 out). I know that the 7MGTE uses a Cam Position Sensor and Coil Packs instead of a distributor, but maybe your CPS is out of alignment, causing it to occasionally fire on the exhaust stroke.

Hope this gives you something to look at and hopefully fix

there is a good chance u could have a faulty coil pac they are known to have problems if the car sits what u need to do is pull each wire and crank test them to see if all are working rite

the thing is the coil pack worked when i removed it from the red supra which you can see on my car domain site (begining of thread)the car did not sit at all actually i got it drove it for a day and wasted no time on the swap, the swap only took me 2 weeks and before i did the swap i drove the red supra around and it ran fine grantit the body and suspension were shot but motor wise it ran and started fine. i literally swapped all parts over from one car to another which is why this makes no sense why my car will not work i just put in new spark plugs and still nothing, but testing the coil pack would not be a bad idea when you mean test them you mean pull each wire out with the spark plug and see if i get spark?
