Problem with check engine light(won't start sometimes)

[Nikola]

I have problem with starting engine ( mostly when is warm) becouse when I put contact ON check engine light didn't come ON and fuel pump isn'tworking
I solve the problem (for now) in few ways
1. Repeatly put ignition ON and OFF
2.Repeatly trying to cranck without pressing the clutch pedal
3.Put the ignition ON and waiting ( after few minutes check engine light and fuel pump is started)
4.In the worst case I leave and came back after one hour nad then normaly started
That is happen aproximatly 3 times of 100 starting, but without any order or reason
I can't investigate hardly, becouse when I start to do same, usualy problem dissapear
I'm afraid that the total colapse will happen when I will be long distance from any help (somewhere in the mountains)( I think that everybody know how difficult is to tow Explorer on four wheel without working engine )
What is the problem and how can I solve?

Possibly a problem with

1) EEC Power Relay or 2) Fuel Pump Relay or 3) Both EEC Power Relay and Fuel Pump Relay

Both relays are located in the Power Distribution Box in the Engine compartment. You should test both relays.

See Figure 29 on this page:

Since the problem is so intermittent, I would replace both relays. They are cheap and easy to install.

I've had this problem a few times. One time it was a relay. Another time, it was a broken ground wire that the ECM uses, which is located near the battery. The third time was a burned out fusible link located near the starter solenoid.

Thanks everybody for sugestions. It was EEC Power Relay. I'm answering so late because I don't have same problem since then till today, and I wait to happen and to be 100% sure that I solve the problem. Thanks again.

Thanks for letting us know what it was. Your information will help other people that have the same problem diagnose their situation, and enable them to repair it on their own.
