This will be a 1995 Landcruiser 4.5L The motor in it came from a 96. I was on my way up to the trail. Right before I left I had cleaned my MAF sensor with CRC brand MAF sensor safe cleaner. At the gate I was goofing around with my scan gauge ii I was looking forward and hitting the buttons trying to clear an PO135 code for my upstream O2 sensor I had replaced that same day. I was not paying attention and accidently hit the mode button and thought I was clearing the code but to find out I forced it out of VPS mode a setting in the scan gauge. I don't know what this is. It got stuck and said connecting. I backed out and went to the clear code this time and cleared the P0135 successfully. This vehicle is highly modified. when I was a couple of blocks away it started falling on its face to the point I had to pull over and turn around to head back to the shop. Just barely getting back I noticed it had no back pressure it coasted just like I had no torque converter had to keep playing with the gas pedal to get back. I made it within 150' from my shop. It turns over but no start. I have been working on it for over 24 hrs now. I smell lots of gas. I removed the spark plugs and they were very wet with gas. I changed the spark plugs they were only 4 months old and looked pretty good. Checked cap rotor and wires. When I crank the motor the engine light is on and when it attempts to sputter the engine light blinks at the rate of it trying to start. I checked all fuses inside and engine compartment also the fusible links. I have all spare fuel relays and swapped them all out along with the igniter and the EFI relay. I tested and changed all the fuses in desperation. I know it didn't make sense to change the fuel pump relays and so on because I smell gas. I have some pretty good automotive skills In my time with this vehicle I have removed the head re-sealed the upper and lower pan gasket changed the timing set and much more. But I now realize this thing has me wondering if I know anything anymore. This thing used to have lots of problems and I have addressed them 1 at a time with good success. I'm stuck on this one. Oh and if I remember correctly one time a couple months ago I had the MAF sensor unplugged because I was changing some stuff on the intake and at startup it wouldn't start. I went back and looked and seen I forgot to plug the MAF sensor in. I plugged it in and it started right up.
