remote start - hard time starting, sounds like fuel....

[RatedR]

I bought the fastback w/ a remote start viper alarm in it. I had to fix it so that it works and all, but now when I start it using the remote start, it seems like its not getting fuel.

I have it wired so that the accessories are working when the remote start activates (a/c works and radio). But when it cranks, it sounds like its not getting fuel. It starts on its own every now and then, but more often it has a problem starting. When I sit in the car and have the remote start go on, it will have the same problem and I'll assist it by pressing the gas pedal and it starts right up. So this is what lead me to think that this is a fuel problem. Anyone know how I can fix this?

i can pretty much give you a guarantee that the second starter wire in your ignition harness is not hooked up to your remote start system. If that wire is not hooked up then it will not start on its own after its been sitting. actually i CAN guarantee that it is not hooked up. have that hooked up and she will start like a beaut every time

I did check on that 2ndary ignition wire. I have both black and red wire (acc) and blue wire (on) hooked up to the remote start relay. Thanks for the info though, but I dont think that's my problem.

I dont think I made myself very clear. The car cranks, the starter wire is not the problem. If I sit in the car while its cranking through the remote start, I can help it by feeding in the throttle a little. This is DEFINITELY a fuel problem. Cranking the car by turning the key, the motor starts right up. If doing it by remote, the motor sounds like its starved for fuel. My question, I guess, should be weather or not there's another wire that should be hooked into the fuel pump circuit.

like i said i can guarantee that it is the second starter wire.. the wire is Black/Yellow. its a cold crank wire also referred to the second starter.. i had the same exact identical problem with my s13 because i installed it before i really knew what i was doin. it would crank and crank but would not start unless the car was already warmed up. if it were cranking and i gave it a little gas it started right up. trust me on this one i am also a certified installer now so ive worked with this stuff hundreds of times. their is not goin to be a wire on your remote start that you can just hook up to the second started but you are goin to have to hook up an external relay. depending on what model you have i can give you a diagram if you like.

Most likely your 2nd Start wire, but I would also re-program the tach to be on the safe side

I see what you're saying, I didn't catch that on the wiring diagram. Thanks! I'm not sure as to what kind of external relay I should add on, but that diagram you spoke of sounds good right about now!

I've tried reprogramming that tach wire, no change on the remote start...it looks like it is that 2nd start wire (black and yellow).

I would just use a bosch relay. here is a diagram.

sorry i guess i could have made it a little bigger

hahah, thanks for the info. Sorry to say, my alarm ended up getting busted last night. For some reason, the unit started going off and wouldn't respond to the transmitter. I pulled off the main wiring harness, and it stopped. Now the damn thing can't recognize the transmitter at all... I guess I'll have to wire a new system up....so that diagram will still be useful~! Thanks again!

lol no problem.. yeah it is a necessity for the remote start to work right.

Wiring the relay that way will do the same thing as connecting the two wires together. You need to cut the second start wire and use 87a for the key side and 30 for the starter side. Then 87 gets the 12 volts.

There is no isolation with that setup. When you turn the key the relay is going to operate when it doesn't have to nor should it need to. You only need the relay for the remote start. Your method would work fine if he is using a remote start with a satellite relay setup like the dei units and was using the trigger (purple) wire. Or any unit with a second start output. Then the relay would only power up when remote started in which case 85 would be the trigger wire and 86 would be 12 volts or vise versa.

he is using a DEI set up and that would work fine.. that is just the easiest way of doin it if everything is already installed and you dont have the second started harness unless he randomly has one sitting around his house which i doubt

I get that part but it needs to be the trigger wire in the ribbon cable and not the start wire. It is not that clear and for someone that is new to this it can be confusing. Just trying to clear things up.

In which case the relay is still needs to be changes like I mentioned in my first post since its a negative trigger.
