Ok guys i've been running into a few odd problems with my truck lately.

#1 For the last year vehicle fails to start when washed or rainy day old distributor was cracked, new ignition coil and control module and distributor still fails to pop off and will actually reverse rotate like timing is off.

# I cant press accelerator past 1/8th pedal, either is extremely lean or flooding out i cant rellay tell it just bogs out and hard starts. fuel pump 2 years old. has vacuum like whistle when i let off gas or when im sitting at stop light. also idles rough like it bounced as though its under load the releases.

Sounds like you may have a vacuum leak. when it is idling spray wd 40 or carb cleaner around where you hear the whistling or around the intake. If you hit the spot it will change idle or even smoke trough the exhaust. Look for cracked or broken hoses too.

Did you check the CMP Retard offset when the distributor was replaced?

Ive had a similar issue w/ mine not starting on hot/humid days or just after raining. I found that by turning the key to accessory position and leave it there for about 10-15 minutes, it starts right up. Now im not sure if its a security reset or im getting water somewhere because its very very intermittent. It will turn over, start and die immediately w/ no response from the accelerator pedal. I hope this helps.

well i think im going to do the upper and lower intake along with upgraded spyderas it almost sounds like its whistling from around there till more pressure is applied with accelerator, hopefully cures atleast my throttle problem. if not once it warms up ill do the pump also
