2G Solenoid bypass start

[the heeat]

Ok, I'm just going to give the readers digest version of my situation, had a fuel issue, changed all, flushed all and have all reinstalled except fuel tank which will go in after work tomorrow.

I, of course, need to start the car in order to make sure my problem is solved. I can't use the ignition switch to start the car, I was told I could use a remote start that some mechanics have but I don't know anyone with one of those, nor can I find one. During my search, I was told I could do some kind of bypass via starter and solenoid.

If anyone can tell me how to do this or a better way, I would greatly appreciate it! Thanks in advance guys!

Why can't you use the ignition switch? You are going to need to have the key in the on position in order for the car to start. You can hook a wire to the trigger post on the solenoid and just touch it to the + side of the battery, but it won't start with the ignition in the off position.

I had to have that interlock system installed (dui) and I think my fuel system stopped up (debris in old tank, or already that's the first problem I'm assessing) and I couldn't take it to be serviced on schedule a is required of the interlock, which results in the inability to start your car until it IS serviced. So i need to start the car w/o using the ignition switch, which the interlock is wired to, so I can determine if I've solved my problem or not.

All i have to do is hook a wire to the solenoid and then touch that to the the pos batt term and it'll crank?

I'd be worried you'd get in legal trouble for that..you might want to call and ask what happens if you have car problems and can't make it to servicing.

Ive spoken with both parties involved and the remote start that mechanics use is what i was told i could do. They all know my situation and are helping as much as they are able. Believe me, I've made sure there are no legal ramifications that will befall me in this situation. So just hook a wire to the solenoid post and "touch" it to positive terminal? What gauge wire should I use? ...of course, car should be in neutral and ignition switched to "on" position...anything else?

 

[NHerron]

Gotcha, just checking

Yeah that's about it Bryan covered it. Tip, instead of reaching all the way around and below the intake manifold, just look for a 2 position connector that has only one wire in. It's a black/yellow stripe IIRC. It will be around the transmission mount, below the thermostat housing area. Wire size should be no smaller than 14 gauge I suppose

So yeah, neutral, run position, jump the solenoid to +12V.

 

[the heeat]

Any chance i can get a pic? Lol

 

[NHerron]

Yeah give me 5

Here it is, just disconnect this and apply +12V. It's the wire for the solenoid.

I don't know exactly where it is stock but it will be in that area.

 

[the heeat]

I just had an idea...do you guys think i could drift start instead? ...since i can't use the ignition i mean.

 

[NHerron]

If thats the same as push starting then yes. But why? You having a hard time finding the connector?

 

[the heeat]

I haven't had a chance to look yet...just got home. I'm not sure how well push starting would work right now considering I just installed a new fuel tank, pump and filter? I haven't even put gas back in the tank yet, but I'm going to when i decide the easiest method of starting the car for a minute. Anything else you can think of that needs to be done prior to my starting it after those installs?

 

[NHerron]

Nothing I can think of, the fuel system primes itself very quickly so you shouldn't need to worry on that one.

Are you trying to crank the motor or actually run it? You aren't going anywhere unless you're going through the ignition switch. The ECU won't have power. You also aren't going anywhere without a fuel tank. Your posts are very confusing. Please clarify.

 

[NHerron]

Hes trying to bypass the interlock. Sounds like it just cuts power to the solenoid, since he cant event get it to crank and the ECU does not control the solenoid. So if he puts key in run and applies power to the solenoid it should start. ECU has power in run position.

I just installed new tank, filter and pump. I just need it to crank so i can determine if there are other problems other than what i just fixed. This its my dd so I'm trying to get it back to dependable. I don't need to physically go anywhere, just want it to run for a few so i can make sure everything works and what else if anything needs repaired/replaced.

 

[pauleyman]

I doubt that interlock is just for the starter. Cranking it won't tell you anything. The starter bypass switches just crank the motor over, nothing else. no fuel pump, no ignition. nothing.

 

[NHerron]

If the interlock only disconnects the solenoid then it will work as long as the key is in the run. Key is in run so it gives the ECU power therefore MPI relay is on and the MPI relay gives all sensors power. As soon as engine starts turning, the crank and cam sensors output a signal therefore spark, injectors, and fuel pump operate.

Correct me if I'm wrong there.

And I would think interlock disconnects the ECU in some way but maybe not and it's just a simple starter disconnect. Maybe the government went cheap on that one!

I would look it up but I'm just too busy today
