I've found many problems in this forum can be a result of a poor ground at the fuse block under the hood on drivers side. This box tends to become loose at the screw(s) where it both grounds and anchors to the vehicles body. I simply removed the screw(s) cleaned with a wire brush, replaced them assuring they are tight. (Problems Solved!!!!!!!) Also would't be a bad idea to remove the cover to this block and check all relays and fuses to make sure they are properly seated. Hope this works for many of you......Reply to me with any updates.

my truck does the same thing, its moisture getting inside a crack in the coil... the best solution i found is spray starting fluid lightly around coil, then air off with computer keyboard aerosol spray air.. will be up and runnin in 3 minuts...
#89 of 108 96 express starting trouble
Oct 13, 2011 (12:47 pm)
I have a 96 Express with the vortec 350. it will only start if I hold the gas pedal to the floor. Once it starts it runs a little rough but able to drive. It will cut out and spit and sputter little but still runs down the road. You can shut it off and have to hold the pedal to the floor to start it again. It does not matter if its hot or cold. Seem to run rich. Its not putting out any codes.Things I have replaced and or ruled out. First I have good gas pressure. And spark seems to be good. I just installed the upgraded fuel injection system, fuel filter,cap,rotor, plugs. all new upper gaskets. MAF is good. Throttle body was cleaned and look to be good. Iam at a loss. Have know clue what it could be.It only has 140,000 mile and I have $700 into it now and it still has not fixed the starting problem. Please let me know what you think. Maybe crank sensor or map?I just know and running out of money to put more parts that dont fix the problem. Thank for any help

#91 of 108 2001 chevy express cold start issue
Nov 17, 2011 (5:11 pm)
hey everyone just noticed most of the issues everyone is having with their expresses or savanas is after the van is warm or hot. here is a new one for you my neighbours express has issues when its cold. the other day i tried to start it to move it and it took all day to get it going finally after almost killing battery i cleaned all contact points inside the cap including rotor finally engine started. however i noticed that two days ago when my neighbour started van it backfired after trying for quite some time anyway to the point of my issue i noticed that once it was going it idled high and very rough, so i had him shut it down and restart it and when he started it the second time the idle was immediately lower and smooth. i was curious as to what sensors actually run at first because i know that the engine was definately not warmed up so it must have been still in closed loop i think. anyone who knows feel free to help as it seems weird that the van on the second try seemed to run perfect.

This Cargo Van will not start, if I take out Air Filter and spray Starting Fluid in it starts and runs, is this the fuel pump? I would think if the pump was out the engine would not run at all.

Have you checked the Mass air flow sensor, here is a link where you don't need a scanner to check it, it's a few steps but it till save you money and the directions are clear as glass:
Common Symptoms of a BAD MAF Sensor
This list is not all inclusive but it does contain the most common symptoms of a BAD MAF Sensor are:
The CHECK ENGINE LIGHT (CEL) on your Instrument Cluster is lit nice and bright with one of the following codes:
P0101 Mass Air Flow System Performance.
P0102 Mass Air Flow Low Frequency.
P0103 Mass Air Flow High Frequency.
Lean and/or Rich code(s).
Fuel Trim code(s).
A tremendous lack of power upon acceleration.
Black smoke coming from the tail-pipe.
Vehicle may idle rough and stall.
