Fuel or Air problem?

A stock 5.0 5spd should be in the high 14s or low 15s if it's an auto.

Don't take that as an absolute, just a guide to what your car can do. My best is a 15.6 @90MPH

I just wanted to ask this, but what were your shift points for each gear. The correct shift points for a stock/near stock 5.0 is 1-2 5300, 2-3 5000, 3-4 4900. If you don't have gears, then you won't even get to use 4th gear.

I didn't want to comment on your track times, but I had to let you know that it's not the end of the world. The first time I got my car I ran 16.5-16.9's all night long. Not launching well, and shifting at 5600-5700 for all the gears is a bad combination.

Now back to your problems. Your fuel pressure seems fine. Don't worry about lack of fuel for right now.

The first thing is to run the trouble codes. If the computer has detected any excessively malfunctioning sensors, then it will spit out a code. The proper procedure is detailed in a Haynes manual.

Next, remove all spark plugs, wires, cap, rotor & inspect them. The plugs all should be dirt brown, and gap should be at .054". If any of them are different, please let us know. The wires should have no breaks in the insulation or obvious damage. The cap/rotor contact points should be shiny brass. If they are not, you need to clean off any corrosion, or easier, replace them.

Then you need to remove the MAF sensor from its housing, and clean it with carb cleaner & a q-tip. I know you cleaned it already, but you may have some slight residue on the sensor wires. Here is a write-up.

Also, do the same for the IAT sensor.

Let us know how it goes.
