#49 of 86 1995 Toyota Tacoma hard start when hot
Aug 16, 2009 (8:00 pm)
I have changed fuel pump, fuel filter, wires, distr. cap, rotar button, fuel regulator still problem exists. Cranks great when engine is cold, but once it gets hot and you turn engine off and let sit for 5-10 minutes it is a hard to start. It takes a long time to turn if over. I had ignition module checked it was ok. Could it be ignition coil going bad? I have been told most of time if it was coil would not crank at all? Please help!!! Thanks

sounds like it may be the cold start injector or the cold start time switch... the timer looks just like a temp sensor, and is right next to the temp sensor at the back of the engine behind the intake( close to where the old chevys had theyre distributors), anyhow take this and unplug it first to see if it makes a difference? then remove it and test it with a multimeter, you can get the specs out of a chiltons, i.e. u need a thermometer and bowl of boiling water to check the full range of the switch. anyhow, u can just replace it if u dont want to go through the trouble os testing it to see if it is good. that should help/ fix your problem thoug. by the way, you do have the 3.0 v-6 correct. if not the switch is in a different location, but still basically called the same thing

My Tacoma is a 2.4 engine. Is this part the same as the engine coolant temp. sensor? Thanks

I have the same truck...I brought mine to the dealer for the same problem you are having...they said my fuel pump is going out...they tested the fuel rail it should be at 40 psi +- mine was at 10 ...being that i drive 55 miles one way to work ...my truck is out of warranty...the new fuel pump can only be purchased from the dealer go figure....its about 671.00 here in la. it also throws the AFR..Air fuel racial sensors off also...the 2 above the catylatic converter and those 2 if bad are about 400+ each..if they are bad good luck getting them out...they usually break...bout 800 for new manifolds....so if under warranty let them fix it and please let me know the outcome my truck is still on ramps at my house due to bad fuel pump i hope.

#55 of 86 1996 hard start when hot
Sep 29, 2009 (6:54 pm)
i've seen so many posts on this problem and not one answer has anybody figured it out. Same problem as others runs great when on but if its hot out with engine hot if i turn it off come 10-15 minutes it wont start. It turns over but the engine will not start if i let it sit for another 10 minutes then it starts and runs great. replace plugs, wires, air filter fuel filter water temp sensor. Please help.

I had this problem for quite some time and changed out plugs, wires, crank sensor, rotor button, cap. I finally figured it out that it was the engine coolant temp. sensor located at the back of the engine. After that it cranked fine even if hot and been sitting for a while. oh yeah changed fuel pump & fuel regulator. I recently experieced coil problems. When the coil starts breaking down it can possibly do this. I replaced my coil because it was trying to stall. I just want to WARN PEOPLE THAT THE MADE IN CHINA COIL THAT ARE SOLD AT YOUR LOCAL PARTS STORE DOES NOT WORK PROPERLY. ONLY A DENSO BY TOYOTA WILL PERFORM CORRECTLY now it runs great!!! Coils at dealership is around $97. It will be worth it to get problem fixed. I have 2.4 liter, automatic.1995.

95 22re. I am having all these same problems....easy to start then hard to start, hesitation, stalling but sometimes it runs just fine. The other symptom I have is a high charging rate. I replaced the alt about 5 months ago and battery bench tested good. Any ideas...i was thinking maybe the fuel pump is shorted out? and causing the high electrical load...It stays pretty constant at about 16 volts and pulsates when blinkers are on...jumps when lights are turned on.
I did the "pull positve lead to batt while running and see if it stays running test" it did but when I tried turning on a/c and headlights the engine died.

i recently replaced the converter shield gasket. after that my rpms cannot climb past 2400 in idle or when i drive. some days the response is boggy and some days it responds fine. i checked the spark plugs got em cleaned. i took the tank off and inspected it, fuel filter was okay as well. this morning as i took the kids to school it couldnt rev past 1500 rpms.
