Yedling has a point, first poster, alter your run time, if it's a tach issue the starter will stay engaged when you turn it on OR it will run 15 seconds only.

How are you going to get tach from the injectors on a diesel?

I would look at crank or camshaft position sensors for tach.

ok....you will do this.....no tach settings with 4 seconds cranking time if you really have a diesel. This setting really works and you will not have this problem anymore..guarantee. I've seen this so many time and it works very good. It will feel that it over cranks when hot but will be cranking beautifully when cold and will not shutdown. You may want to change your running time to 60 minutes.

The tach wire is also used as a safety measure. It will kill the engine if it sees an over-revving situation. I myself would do the extra footwork to connect to something. Injectors will have 2 wires on each injector, they will have 1 color wire that is present on all injectors. The other colored wire of any injector is the one you want to use.

I agree that connecting to tach is a security measure. I found the tach or injector on Ford trucks are really unstable. On gas ford f250, injector works very well, on diesel trucks, no tach with 4 sec. cranking time as worked wonders for me. I have hundreds of diesel Ford trucks on the road setup like this and I have absolutely no come backs. It's really your choice.

guys, I am kinda lost here. The OP said he can start the car, but it turns off after 4-5minutes of running. So I thought cranking time should not be a problem, right? because by the time the car shut down, the crank has been released long ago. am I right here?

Hey Yeding...your right crank time is not an issue, I actually have it set for three seconds crank time (i have a diesel) it starts fine, lately it has been operating good. the past few times i've used the remote start it was working fine. At first i thought maybe i was hitting the shutdown button because the unit is touchy.

off topic I must say the key fob for the 5902 is absolutely horrible.....the buttons are too easy to activate, and when you use the lock out function it makes the remote awkward to use. They should have designed the transmitter with a nice spring loaded hard shell flip open lid.

X2 with comments ref the remotes. The joke is just before the takeover 5 or 6 years ago, Clifford brought out the A/Guard 5 with an absolutely brilliant TOUCH SCREEN remote and DEI canned it, probably too good for the cheapskates.

hi, wmccue,

I actually had a similar problem previsouly, I have a gas engine though. You can do the shut down diagnostic test, it will tell you what shut down the car. The problem I had is the car was shut down by over-rev protection, and it was fixed by getting the tach signal from fuel injector instead of the coil pack. there's something about the ford veichle that you will have to find the clean tach signal source. maynot be the same problem as yours, but definitely run the shut down test first.

Four second crank? Even on an 01 F Series truck? I didn't realize the 01 has factory over-crank protection? I didn't think that it was introduced until a few years later.

To the O/P...as already mentioned, check your shutdown diagnostics for the reason the RS is shutting down. Virtual tach partially relies on voltage...is your alternator working 100%?

I'm talking about diesel trucks, f250...f350...f450...not a for f150 because it normally works good on virtual tach or injector connection. 4 sec cranking time is only for diesel trucks.

Again, I did not think that the 01 vehicles, diesel or otherwise, had any type of over crank protection. A 4 second crank time is way too long IMO, especially in warmer months. A tach wire connection is the only way to do it properly in the older vehicles, IMO.
