Performed "Brain Surgery" last night (cost me less than $6). Now my YJ fires up the first-time, every time. Thanks to sasquachYJ for the original post...you saved me over $250!!

I'm going through this right now. Thought I was crazy. Everyone tells me I need a new fuel pump cause I'm not priming, or check back valve is bad. But as soon as that CEL comes on I start EVERYTIME! This thread rocks....this reply will help me find it again later when I attempt surgery.

Nice pictures NOT!! whats the point in having a write up if you just end up deleteing the pictures. i give this a 2 thumbs down..

Side Effects may include dry mouth, nausea, vomitting, water retention, painful recolage, hallucination, dementia, psycosis, coma, death, and halitosus. YJs are not for everyone please consult your physician before use.

I only read the pictures!

I had no difficulty at all doing it without pictures. I actually took a few until my camera batteries died and I couldn't locate more. Sorry for the blurriness, also an effect of low batteries.

Any suggestions for the silicone?

Radio Shack dosen't carry a specific 'electronic silicone' anymore. I fully understand the non-latex silicone requirement, but would any clear non-latex silicone do?

I went with the smallest removal of silicone on the backside. Makes it harder... the old silicone is a pain to remove - plus is smells rotten when it hits the soldering iron.

If you have the 4.0, the capacitors are in a different spot on the ECU. But there are still 3 of them. They are easy to spot. This write-up worked great for me, fuel pump kicks on every time.
