I have a 85 camero with a 2.8 liter V-6 fuel injection. I am rebuilding it for my daughter who turned 16. It was running but running rough. I changed the plugs, rotor bug rotor cap and wires. Now it will not start at all. It has good spark and plenty of pressure at the fuel rail. Any suggestion to what I may have done during this tune up. I can't even find any wires I could have knocked loose.[:@]

 

Recheck your work being that it ran before you worked on it. Make sure the spark plug wire go where they are supposed to go.

 

What is bad. I have a chiltons and checked and rechecked and made sure everything is in order but I now there is something probably small I'm missing. Maybe the head up a$@.

 

I went over everything again tonight with two other guys looking over my shoulder and the only thing is the spark from a old plug was more of a white than a blue color. I am going to change out the coil pack. What do you think.

 

check your gap and firing order chilton is bad for stating which bank is number 1 cylinder and also i have found them to put the wrong plug gap in the manual also. i recently had a fellow co-worker who did a tuneup on our service truck good mechanic just didnt realize what he was doing at the time. he came to me ask for my help , he stated all he did was replace the plugwires and plugs. the truck ran before but wouldnt start after. i checked the wires first they were correct then asked him what gap he set the plugs on, he told me .060" and i informed him that was wrong for the ignition sysytem that particular chevy truck had. he argued that the manual chilton manual said .060. i told him the quickest way to see if i was right was to gap 4 plugs at .045" on one side of the motor, if it started but ran like crap he needed to change the other gaps. i guess you can tell what happened the manual was wrong. so, to make a long story longer check your plug gap against the old plugs or the emission label under the hood. it will most likey be .045 0r .060.

 

Thanks everyone, I replaced the coil tonight to see if that was the problem and it still did not start I will check the plug gap. I also pulled the distibutor tonight and the thing is rusted inside and the magnet has two cracks in it. I'm going to go ahead and change it out.What do you think besides rechecking the plug gap???[&:]

 

i would stick to the plugs, i bet if you put the old ones back in it will start. one other accurance of this i dealt with was with my father-in-laws car. it was an olds 305, we put new plugs in ac delcos they didnt' have the original plugs anymore and were superceded. it ran before we put them in and after nothing. we put the 4 on the drivers side in and it started and fumbled around a little but started. went to the parts store and purchased new autolites( i have never had any problems with autolites) put them in and it ran like a champ. not sure if the new ac delcos we put in were bad or just not the wrong plug but the autolites worked great. i have had bad plugs new in the box before, it happens, but most likely you have the wrong gap. if your chilton manual says .060" try gapping them at .045"
