Hello 4runner-mates,
Has anyone dealt with a slow start?

* The spin speed seems the same, but once It gets into the firing stage, it starts "coughing slowly". Probably the sound is similar to the sound made when not enough gasoline is reaching to the system.There os some much other garbage on vehicles these days who knows, but how fast does it spin over? Is this the same speed all the way through the starting cycle? Next question, have you checked the fuel pressure with a gauge. The battery need to be checked with a battery load tester. Almost any auto parts store will have a load tester, and a fuel pressure test kit that you can rent. It also could be a security issue with the BCM, or ECM whatever one the security system is in.
I wasn't familiar with that. But yes, the process flow is quite complex, so seems like hundreds of potential root problems exists.You may or may not know this, but the starter is tied into the BCM. So when you turn the key, the BCM is what sends a signal to the starter and starts the engine. Once the engine starts, the BCM tell the starter that the engine is started and to turns off its power. What those paramators are IDK. I also have a 2004 4 runner. The BCM, and ECM communiate with each other during the starting process.
* Nope, I haven't done the pressure test yet - this is the next step. ( together with testing the coil on plug packs & the wiring for grounding)When did you last change the fuel filter and have you tested the holding pressure of the fuel line from the tank to the engine? Had a fuel line that was dry-rotted/cracked that would let the fuel drain back to the tank after sitting a while. The fuel pressure check is where I would start as previously recommended. Have you tested the coil on plug packs & the wiring for grounding?
Hm, that's very probable. Now I wonder how I can check the GPM fuel it delivers. Would toyata's techstream catch such a reading?Yes it is in the tank and polymer tanks don't have the rust/sludge problems the old tanks did. My thinking was your statement that after sitting for a few hours or overnight the hard start problem occurs. "If" there is debris in the filter it would settle to the bottom of the filter and when you try to start it would rise to plug/restrict the flow. I would want to know the volume (GPM) it puts out on the first start and on the after it starts mode. The fuel stations in many locations receive bulk fuel and if the station is the last on the delivery list or their tanks are sub par you get trash/water/sludge etc. which stays in the filter. Not saying it is but for me I'd like to know before I go deep into the system. Pressure test tells you how much pressure but nothing about volume, just MHO.
I went to a shop, they checked the fuel pump and also told me that the initial pressure was fine.Did you get it figured out?
