Route the original 3.4L fuel supply hose along the firewall main rail to passenger side of the engine bay. Install the provided high pressure fuel hose to the end of the 3.4L Fuel Hose Extension. Route this hose down the firewall to the line and union below. Connect the high pressure Fuel Hose Extension to the fuel supply line. Tighten all fittings.
Hi, thanks for responding to my posting. Actually, stepping on the gas has a very negative effect - it won’t start at all.
To get it to start when hot outside (this never happens when the ambient temp. Is under 80F) I have to engage the starter for some time (15-20 seconds which seems like a long time) until it eventually catches.
When it starts it does so very gradually (hard to explain I can tell that the motor is trying to start, but it starts slowly, then normal - if I step on the gas too early it seems to stop it from starting). Since this problem doesn’t happen during colder weather, my thought was that it wasn’t a fuel leak. Your second opinion was that it could be that the computer is commanding a “cold start.” What sensor(s) should I consider replacing to fix this problem? Well I spoke too soon.
Worked fine for a couple days but went back to its old ways. Took it to another shop and they thought they knew the problem and cleaned the EGR valve and replaced a shot rotor and put in new plugs and did something with a Vacuum switching valve. Still acting up!!! What really honks me off is that these places act like they know exactly what it is and they obviously have no idea. Are there any real mechanics out there any more? I think I’ll try the water temperature sensor thing from spaulding1 below. Hi All,I did a search for “1996 Toyota Tacoma Hot Start Problem” and came to this discussion.
My Tacoma would not start after sitting for 10-15 minutes. If I let it “Cool down” an additional 10-20 minutes it would start up like nothing had ever happened. I disconnected the 2 wire connector to the sensor? On the air filter box.Started up no problem, reconnected - would not start.
I left it disconnected and (Aside from the “Check Engine” indicator staying on) its running normally. I do not know what the “senor” is for, but I’ll be heading to the dealer to buy a replacement.
Hope this helps By the way the weather has been warm to hot (80’s -90 degrees)here in SoCal. The item you’re referring to is called the air filter barometric pressure sensor and the other thing aforementioned is called the coolant temperature sensor, or at least that’s what the guy at AutoZone calls them. Supposedly they work “hand-in-hand” on startup. The bottom line is that the air filter sensor thing is easy to replace and costs around $50. The coolant temp sensor is a bit harder to fix but only costs around $25. It’s getting cooler here in Indiana now so its getting harder to replicate the problem.
Will probably have to wait till next summer to see if its really fixed or not. Would be interested to know if the air filter sensor worked though.
