Does it act the same way with the HAZARD switched to ON?

Slow fuel leak at the Fuel Pressure Regulator (FPR).

Using a voltmeter or 12vdc testlight (preferred) check for Battery_Voltage_(B+) on the following pins (use battery_negative terminal for ground): D1_5: B+ (Hot at all times) D1_6: At KEY ON only (B+ (Hot for 2-3 seconds)). During CRANK Hot at all times. D2_4: B+ (Hot during KEY ON and Hot during CRANK).

Funny, I see it was there.

2.5L or 4.0L?

Long live Cruiser's tips. You'll be missed.

Make sure D2_4 stays HOT during KEY ON, CRANK and ENGINE RUNNING.

@Samohtgaoh Welcome to CC. Post your VIN in the Forums under 'Comanche Registry/1988'. Someone can get you your vehicle build sheet.

Make sure the bleeders aren't plug.

Works perfect. Those without WORD will need help.

Cruise Control ground, if equipped.

@Pete M I think you can post WORD.docs. Try it nothing to loss.

Start with the language used. Learn the history of the units involved. Meet the men and women named for these units. This helped me with perspective. Some great chapters on electricity. The World of Measurements

I think it had something to do with assembly. Ease of mounting to fastener. Quicker for the robots.

B1 & B2. I understand now.

Try swapping both O2 sensors. Make sure problem doesn't follow the sensor. Maybe make jumper wires, PRE to POST and visa versa.

One more thing, that hose clamp looks like it missed it mark. Needs to move up the hose, could cause problems later down the road somewhere.

That vacuum cap has cracks in it. Could be a vacuum leak.

What's your ST & LT Fuel Trim values? Looks like your running LEAN. Check your manifold bolts.

Maybe post a photo of your radio. @Minuit Any insight here. ↑↑↑
