I would replace the fuel pump relay, and the engine speed sensor. I would need more information to rule one or the other out, but at this mileage, neither part is terribly expensive, and both have been known to cause your same exact condition

Our 1999 blazer seems to have starting issues only when the weather is wet or damp. 113,000 miles with 4.3ltr engine. It will start if you aggressively pump the accelerator. No other problems starting...


I'd have a free scan at parts store for any trouble codes first , just in case, if no codes come up then I'd consider a new cap & wire set. One of , or the most common problem with hard start in wet/damp weather is plug wires & cap, especially if they haven't been changed that you know of since new.

Fuel supply module


Check fuses for fuel pumps, and the crank angle sensor on the back of the motor. Also check fuel pressure to make sure you are getting any fuel at all.

Also check fuel pump relay (white one in back of the fuse panel behind the cig ash tray). They last abaout 10 years and then they quit.
