well it was starting and i replaced plugs and wires and coil paks and it didnt want to start but finally did and turned over but left alone for a 10-15 now it wont start just turn over until battery discharges really need some suggestions without 1000 dollar price tag

Do you have a bosh or Gems Motor?

You can check for spark with one of the old plugs hooked up and laying on a manifold.

You can check for fuel pressure at the passenger side fuel rail (4.0 GEMS) with a tire gauge, 32-34 PSI expected. Pump should run for about 2 seconds when key is turned to position 2.

If fuse for injectors is popped, the injectors won't have power to squirt.

If the wires were easy you have a Gems.
why did you replace the coils?
have you double checked the firing order?
have you double checked the 12vt wiring to the coil pak?

its a BOSCH COULD THE TEMPERATURE SENSOR HAVE SOMETHING TO DO WITH IT AND ALSO ONCE IT STARTS ITS RUNNING FINE BUT CUT OFF TO THE POINT OF GETTING COLD OR COOLING OFF IT WONT START AND BY THE TIME IT DOES THE BATTERY IS TO LOW BUT THE CODE I WAS READING READ 1667 BUT WOULD THIS CAUSE IT TO NOT START

I was also told that because it has a cold start sensor this could also be the issue having to replace the temp. Sensor or cam sensor
confusing
