No Start strange ticking

[loots06]

So I was trying to figure out why my IAT were so high and figured out that the intercooler pump would come on and off at different times. I tired to test the pump by bypassing the relay using a wire at the relay but no luck. Immediately after I started having this ticking sound which I traced to the throttle body and now my car does not start at all.

I disconnected the battery and tried reflashing the ECU but still get nothing. I have to disconnect the TB electronics and reconnected it just to get the car to turn over but it still does not start. It sounds like it's not getting any fuel. I'm completely lost at this point. Below is a video...

First disconnect the Intercooler pump by pulling the fuse and seeing if the car starts then. If not with the pump still disconnected try putting a charger booster box on and charging the battery to see if it starts then. If after letting the battery charge the car starts without the He pump connected, measure the voltage across the battery. It should be about 14.0 vdc. If its was low, switch the meter to AC and see if you read any AC voltage. You should see less than 0.250VAC. If you see more than that and the DC voltage with the car running is below about 12.2vdc the alternator is likely failed and needs replaced. Might wish to replace the battery as well if its old.

If the car starts and the voltage across the battery is like 14.1 vdc (with no charger connected) , let it run and build up the battery for a while. Then shut it off and start again (Intercooler pump still disconnected). IF it starts, measure the voltage again. Then shut the car off and hook up the Intercooler pump. restart the car and measure the voltage. If there is a big sag in DC voltage the Intercooler pump is bad pulling the voltage down on the system and causing your trouble most likely and needs to be replaced.

If the problem started up right after you tried to jumper the Intercooler pump relay you may have blown fuses F47, F40 or damaged the PCM cnotrol relay. They are under the hood in the same Bussed Electrical Center you likely sought a 12vdc source to jumper that relay from. F19 you may wish to check as wellas it supplies voltage to the Fuel pump relay. Never a good idea to just find 12vdc to jump test something. Take it straight from the battery terminal to avoid blowing fuses or burning fuse links up if you have to jumper test something IMHO.

If everything is still the same, the car still won't start with the pump disconnected and a charger hooked up we will go further then.

I love my car but hate when this happens. I really can't complain to much because the car has been pretty good to me. I'm sure I'll figure this out but it's just gonna take some time..anyway, I have dashes on the dash with a DTE ORO DATA ERR. I uninstalled the tune and then re flashed but still no luck.

I pulled the fuse and tried to start it but no luck at all. The battery has plenty of power and th car turns over with no issue but still no start.

Found by luck, simple blown fuse

Always start with Basics!

Let me guess...F47

So what about the IC pump issue which is what you were hunting when you apparently tried top jump 12vdc to it and blew that fuse?

IAT's are high and the pump is not coming on. I need to figure out what is going on.

One of three components. The pump, the relay, or the fuse. Sorry to state the obvious. Pump runs at key on. It is not thermally controlled on the Intercooler system. Otherwise its wiring which is possible but not probable. Can you get to the pump without pulling the front fascia?

nice looking car btw. Amazes me what you guys can get away with with all of the BS CARB crap out there. That's the one thing I don't miss about living in San Diego any longer, the other thing is cost of housing.

It turned out to be the pump. I'm glad I had an extra one that was up for sale and never sold. I'm happy to say all is well now.

In regards to the CARB stuff, I hear you man, Most of my stuff is legal minus the cams but i think I could deal with that I hope so anyway because my car is up for SMOG next year. Housing prices do suck fortunately we were able to buy when the market was down, 400K.
