Having Trouble Starting: Ignition Coils?

[mp88]

I may be beating around the bush here, but a second opinion could really help me.
For a while I was having problems with the Explorer. With starting and running. It turned out to be that I needed a new mass air flow sensor.
Now (when the truck is hot). It will turn over, rev to about 500rpm, sputter and die a slow painful death. I took the spark plug wires off the ignition coils, the resistance of the coils is in the 13.8-14.8 ohms range. The manual suggests that the working range is 6.5-11.5 or something of that sort.
A friend suggested it may be my fuel injection. So to make sure it wasn't the fuel injection, I jump started the car (when it wouldn't start) and it revved right up and held it.
It seems to me this is an electrical problem and not a fuel problem. What do some of you think?

the resistance of the coils is in the 13.8-14.8 ohms range. The manual suggests that the working range is 6.5-11.5 or something of that sort.

If the all of the coils resistance is within that range (all uniform), I think they're OK. Temperature has a very big bearing on resistance values.

That sounds like a fuel pressue problem, maybe a weak fuel pump.....?

I agree, sounds more like a fuel delivery problem than anything else. check the fuel pump relay to make sure it's not dropping out, easy test is to swap it for the A/C?(there are 3 of them in mine all next to each other in the electrical box by the firewall and brake booster) relay.

Ign coils generally work or they don't.
