Running pressure should be 54psi for a CPI injection system. Old TBI was 12 psi so theres your problem - low running pressure so it staves out. CPIs have a pressure reg and 2 lines under the upper intake housing that are a known leakage/problem area but so is the pump. No crank sensor on yours - these older distributers had the sensor and pickup internal to the dist.

I have a 1995 gmc jimmy 4.3. It seems to be a bit sluggish, like it's holding back. I've driven others and mine seems to be odd man out. I've had the cap and rotor changed as well as the plugs. I tried regular and premium gas but no change. Any ideas?

Depends on mileage and your maintainance. Over 100k is full tuneup and 95 are known to have leakly CPI and nut kit but usually have a gas smell or washed intake (internal). Check the posts on CPI. Also any codes or SES light on, check all vac hoses cause these always rot out and follow to the reserviotr in the drivers side fender.

Hi,
I dont seem to know the differences between the Chevrolt Blazer and the GMC Jimmy. Can someone point out the differences to me... which is better, mechanically and functional. Are they exactly the same size? They seem the same to me.... please help.. anyone?
Thanks Hector

Trim and wheels diff but all the running gear is same - Olds is AWD only so stay away from that. 98Up went to dual depowered airbags and added rear discs. The Autotrac option (4th button) allows 4wd on pavement and is in LTs but over 100k miles some have xfer case chatter cause they have clutch packs in them - not sometime most use or need to. 96up went to updated injection system.

A bit old for me but those did not have airbags did they - if not forget adding one - if they did in the steering wheel simple job to get one at the junk yard and install.
But if this is an S-10 Blazer not full size thats a 2.8L car motor or a small 2.5L 4 cyl - I would really think twice before getting into one 20 years old unless you work on vehicles cause you will have to alot.

Has your Jimmy had any hot day starting problems since replacing the pickup coil? Now that it is summer my Jimmy symptoms sound a lot like yours. let me know, it has been a 3 year mystery for me...lucky Cannada has only 2 months of hot weather.
