Hard starting..

Hi guys i have a 88 cougar xr7 with 5.0 my prob is when i start it, it just cranks, unless i hold to floor the fires up and runs, its not flooding out. car burns the tires, i know it needs iac valve but that shouldnt make it so i have to floor it to start....no mods all stock...:evilgrin:

Pull the codes, click on My DIY link and you'll see how

With the throttlebody completely closed turn your key forward and you should have less than 1 V DC on the green wire to ground at the TPS
It's best to use an buttstuffog meter to move the throttlebody open slowly as you watch the needle on your meter and if it deflects at all you have a interment open in the TPS

There are many things you could check that first start with pulling the codes

And by the way you guys may not get storms out there in Tacoma because it probably rains 80% of the time but out east there are a lot of distracted people right now over the latest storm so please be patient

lol.. sorry guys...forgot about storm....wouldnt the tps cause lags in throttle? i have no lag...burn the tires on demand....it acts like no gas....but when you floor it it starts right up..its NOT flooding out....i know the iac is bad i have unplugged or it will idle at 2,000 rpm lol...

Check the TPS and go from their. If you think it is fuel delivery give it a squirt of starting FLUID. Once again the tps at full voltage pedal to the METAL is in clear flood mode. That means the injectors do not SQUIRT FUEL. If they do the TPS is not sending the correct info to the ECM. Just a thought!!!


Note i am with DAMINC. It is the weekend no power except back up generators. Thank god for my GENERATOR. Keeps the BEER COLD and goes down smooth with some chips and sandwiches. Do some testing and post back. OH YES if the DAM IAC IS BAD REPLACE THE GOD DAM THING. Just a suggestion. Thanks The DARK is making me NUTS!!! Good luck!!!
