I NEED HELP!!!

I WAS WONDERING IF THERE WAS ANYONE THAT CAN HELP ME OUT WITH A PROBLEM THAT I'M HAVING.... I HAVE A 95 ISUZU PICKUP WITH THE 4ZD1 2.3 WITH SOME WORK, NOW HERE

Maybe a valve messed up. My honda did that crap. Finally I did a compression test and had no compression in the # 3 cylinder

mined did that but missed from 1/2 throtle to full. my boss said i might want to chech the compersion so i did and my dad said to retourk the head

OK SO I TRIED WHAT YOU GUYS SAID AND THE FIRST 3 CYLINDERS CAME OUT TO 160 + OR - 2 AN THE 4 CYLINDER CAME OUT TO 170....THE SPEC ARE BETWEEN 128 AND 171 SO I'M NOW AT A COMPLETE LOST...LOL

Check your fuel pressure. I had a severe lack of power and misses at all different times. Thought I had real problems until I checked the fuel pressure and it was low. Should be around 35 or something for a fuel injected and maybe like 15 for a carburated one. I replaced my fuel pump and that was it. It ended up being really clogged with shavings from my aluminum fuel cell. If it's not that check the fuel filter and regulator. Don't look too far into it though. Start with the basic three fuel, spark, and ignition (I think that's right). Best of luck and lemme know if you wanna buy my engine. Tranny and all for $650.

have you changed your fuel filter latly and in stead of doing a comp check try a leak down test

* fuel, spark and compression. ignition and spark are the same thing.

i second that notion. fuel pressure.

check your vacuum lines
