Check engine Light 97 E-150 van

Hello, Could some one tell me where to look for this problem? I have taking this van to two shops and auto zone. For some reason their check engine computer dose not come on i think its a blown fuse,The first shop i took it to about a year ago they thought they found the problem 1/2 mile from their shop and $35 latter i heard a small pop sound and my light came back on they said they replaced the fuse. now i checked all my fuses and their checking fine.

Doc here,

Basics first...Check the bulb ..It might have blown from olde age, after it began working when repaired last..

Not much involved with it as it is a "Non User serviceable" item, other than just replacement of the bulb....

just the wires between the laminate card (IP panel) and the computer backplane connector..could be the laminate card is dirty and not contacting the bulb socket insert..or a wire has pulled..or an open trace on the laminate card. Or a bad IP ground..

My vote is for the blown bulb..

Doc

f your check engine light is coming on it is not a fuse. You have a problem with the engine. If they hook up the scan tool right it should code out as to what set off the check engine light. The next time the light comes on drive it straight to somewhere that they can check it without shutting it off. That should tell you where your problem lies.

Doc here,

Wait, I read your post as the LIGHT would not LIGHT up during key on cycles..

Did I get that right?

If so check the check engine light in the Instrument cluster...If it is good, Go to the Fuse panel and check the computer fuse (though I can't see how it would run without it)

You say the SCAN TOOL won't power up either? You may have power / Ground issues..

Doc

Nomad....you are going to have to clarify a little more. When you first turn on the key, without starting the vehicle, does the check engine light come on? If so does it go off after the vehicle is running? Then does the check engine light come on while you are driving? If it is coming on while driving, then the computer will hold a code to show what the problem is. If you are taking it to AutoZone or such, maybe they are not using the correct scan tool or do not know how to use it. But your computer will hold a code until that code is cleared out.

Kevin, Yes when i turn the key the light comes on, when the engine is running the light stays on. I have taken it to within the week and a half to a auto mech shop and they said they could'nt get their scan tool to lite up either. I have tryed to take pos battery cable off for 5 mins, reconect, lite stays off for a couple of mins then comes right back on. Hope this helps a little. Nomad

Sounds like you have no power to the Data link connector. This is a problem but it may not be the reason your service engine soon light is on. You need to address the no DLC power first to gain access to the codes stored in the PCM.
