97 LS cranks but won't start, help!
 

Only upgrades are Intake and Exhaust...

My car now has spark, battery power, and the smell of fuel. timing belt is in tact and cam gears are lined up with "Up" parrallel to each other.

The car turns over and cranks strong, but never seems to want to fire to get it started. The exhaust makes a slight popping sound, occasionally a louder backfire when I try to start after not starting for awhile. I just noticed that the PCV valve is broken and I will replace in the morning.

My other concern is that the car is not throwing any codes, so I am taking into consideration my ecu may be done for. Is there a way to test it, also, would resetting it have any beneficial value? Thanks in advance...

sounds like ur timing is off some how. not really sure about that one though. could be the ecu. get another one and hook it up.

When was the last time you replaced Dist. Cap, Rotor, and Plugs?

When was the last time the engine ran?

check the cap rotor plugs....how long has the car sat? also check the fuel filter...u may smell fuel but your not getting enough of it possibly

Cap, rotor, plugs, plug wires, coil and ICM have all already been replaced. Where is the fuel filter and how do I check it? The last time the car ran was last sunday, the day it died...

Check your cap & rotor again. Did you replace it recently?

how recently did you replace the cap and rotor? are you sure you got the wires in the right order...if you dont its going to run extremely rough or not at all. also make sure you put the cap and rotor back on correctly.

i dont have a pic of the fuel filter location right on me...if i remember ill upload one tommorow..but if your looking under the hood look on the firewall right straight back from the left side of the valve cover...should see it there.. black unit with a line coming to the top of it and bottom of it

the filter itself looks like this:

I'll have to check it, and all of the ignition parts mentioned were replaced about a week ago, the day after the car died.

Problem fixed! Thanks everyone for the feedback.

Don't leave us in the dark... What was the problem?
