I have a 90 4runner with the 3.0 v6.It died on the way home and i had it towed to my place,Changed the coil and ignitor but I'm still not getting a spark from the coil also the check engine light came on.Any ideas would be greatly appreciated.
Thank you

Get the stored codes from the ECM if there are any. If the cause is not obvious from the stored codes that caused the check-engine light, download the FSM for your truck from the sticky link at the top of this forum and go through the ignition troubleshooting.

No code reader is necessary. Just need to short two terminals in the connector. See the description on page 4 of the folowing article:


See the other articles in the FAQ thread related to OBDI engines:

I keep looking at the codes but have no idea what I'm looking at....So I'm giving up and taking it to a mechanic,thanks for all the help I do apprciate it.

One thing that is kinda wierd.My battery is almost dead but when I try to start it I get spark from the coil.But when I hook up jumper cables I can't get a spark
