Jan 26, 2012 (8:41 pm)
i have a 1995 chevy blazer 4wd, 4.3. when i start driving, its when i hit the gas it sounds like it wants to stop. like there isnt enough fuel getting to it. i took it to a mechanic and he checked the code, it was egr valve, he took it apart, cleaned it, put it back and cleared the code. said it would take 2 days til it ran smooth again. 3 days ago. still doing it, now flashing check engine soon multiple times, sounds like it is chugging......im thinking fuel pump or filter. please, any help or ideas

Remember Ford did not have to take the bailout. But Government motors and doop did. Lol
The recent world reports on the most reliable cars and trucks is Ford. yes they had their moments of trouble, but, all the manufacturers in america did then. But now Ford is a real world contender and they always had the best truck. So yes your decision to buy a ford next time is a wise one. Chevy trucks are no more than glorified cars anyway.

hey, remember one thing, unless you do need to haul in the bed 4000 plus pounds or more, you only need a ford f 150, the 2012 model payload capacity from ther ford website is 3060lbs. that is more than the 2500 hd chevy. so remember the f-150m is the same as the 2500 chevy and the 3500 dodge.

Not to be rude, But General Motors has had its issues, But alot of the farms i've been to or worked on all have GM work trucks with over 400k on them, I rarely hear of fords with more then 250 before they completely run dry. I personally own a 96 Jimmy and it has 325 000 on it. The only problem is the fuel pump (I was not told by a shop mechanic, My father trains Dealership mechanics in Saskatchewan) So for anyone reading this, Chevy and GMC are some of the most reliable and dependable vehicles. Save for some engineering issues.

The "spider" fuel distribution assembly is a sore spot on the 1992-1995 4.3L engines with CPI (Central Port Injection). GM changed the design in 1996 to SCPI (Sequential Central Port Injection)
The problem with the 1992 - 1995 CPI system found on the 4.3L "W" engines can be traced to a defective fuel pressure regulator. The fuel pressure regulator on the CPI system could not be serviced separately from the fuel distribution "spider" assembly. Dorman Products recognized the problem and introduced a fuel pressure regulator that could be serviced separately from the fuel distribution assembly (spider). Dorman #55162 is a fuel pressure regulator for the 1992-1995 CPI found on the VIN "W" engines . The Dorman 55162 fuel pressure regulator cost $35 but the labor cost will be the same as it would be if you replaced the entire CPI fuel distribution assembly (spider). Replacing the fuel pressure regulator on the CPI will save about $250 compared to replacing the entire fuel distribution assembly.

I had the same problem, not sure if this will help but mine was caused by a cracked spark plug.. like you said it sounded like it was gona die and kinda sputtered.. not sure if that is it but i would check the spark plugs

could this be the oil pressure unit at the top back of the engine.. i read it will get old and kill the power or something to the fuel pump...
#470 of 496 Bad ignition wire
Mar 24, 2012 (2:34 am)
Just one ignition cable can cause the ICM (Ignition Contriol Module) to deliver the wrong firing sequence or even stop working until the cable is removed from the source of the ground. For example my friend replaced the spark plugs on my S10 Blazer and did not put the ignition cables properly in the wire looms. One of the cables lay against the hot exhaust manifold and burned through the insulation. When the conductors grounded against the exhaust manifold, it caused the ICM to stop working intermittently but when the wind blew the ignition cable off the manifold, the engine started running properly again. I found the bad cable and put all the cable through the wire looms and the engine never misses a beat. I have since replaced the ignition cables with the correct AC Delco ignition cable kit. If you have lost any of the oroginal wire looms, a new wire loom kit is available. AC Delco 8073 (GM 12073948) for $4.50. Dorman also has the same looms in various assortments of 2, 3 and 4 wire looms under part numbers 40283, 40284, 40286, 40281, 40288, 40289, 40291, etc. If Dorman went to the trouble to manufacture that many different GM wire looms / holders, they must be important parts.
It is important to make sure the ignition cables are in the wire looms and are in good condition. Ignition cables should be replaced at 30,000 mile intervals along with the distributor cap and rotor. GM sold individual ignition cables for customers who found one or two damaged cables. However, GM stopped that practice and now GM only sells complete ignition cable sets, just like the all the aftermarket suppliers.
