Your engine computer is going bad. There are three capacitors inside the ecu that are going bad, unable to hold current. You can replace the entire ecu or try and change out the capacitors in your ecu. It's a common problem with early 90's jeep ecu's.

Where is the neutral safety switch located on my 2008 Jeep wrangler?


Sounds like you're starting at the expensive end and working backwards! First, check your battery, make sure it has a good charge. Second step is the starter solenoid. Some designs have external solenoids, some are internal. Third is the starter itself. Once you are sure all that stuff is good, THEN it's time to start looking for the neutral safety switch.

The check engine light is meaningless when the engine is not running.

Problem starting


If the check engine light does NOT come on when cranking, at the times when it won't start, and the relays are clicking and buzzing, then your ECU is in need of repair. The engine will only start after the check engine light comes on and the ecu is what controls that. ECU is likely going bad, causing the delayed start problem typical of early 90's jeeps. Reasonably priced repair or replacement services for your jeep ECU are available on ebay.

94 wrangler 4.0 fuel pump wont turn on


If your check engine light does not illuminate when you turn the ignition on then your jeep ecu is in need of repair. The check engine light has to be on for the fuel pump to get power. Try leaving the ignition key in the on position for a few minutes to see if the check engine light does eventually come on and if the fuel pump starts to work then.

1994 jeep wrangler no power to coil.....will crank....wont start....changed cps....still does not start....flywheel problem? help...thanx


Is the check engine light lighting up on the dashboard, when you turn the ignition key to on? If not then your ecu is in need of repair since it is not sending power to the coil and probably also not to the injectors also.

1995 JEEP WRANGLER 2.5L HARD START COLD 1 START OF THE DAY


When you're trying to start it for the first time of the day, look at the dash to see if the check engine light is on when you first turn on the ignition. If the check engine light is not lit up, your Jeep ecu is in need of repair and the vehicle will not start until that check engine light finally comes on.

Hi can u help me plz my 1994 jeep grand cherokee laredo 4.0L Automatic have problem with it before I start my jeep, i have to let it sit with the key in the "on" position for 5-10 min may be more...


Your ecm is going bad. If you haven't noticed yet, the vehicle will only start once the check engine light comes on, on the dash. That's the ecm finally sending power to the relays that feed the fuel pump and ignition systems. If you're mechanically and electrically handy you can remove the ecm, disassemble it and replace the three power capacitors inside. If not, just have the ecm checked and replaced.
