It cranks for a min but sounds like it is running out of gas and then kills out-
2/2/2013 BillNot sure why you decided to replace 2 spark plugs. Try unplugging the MAF and see if it will run. Don;t think I'm getting all the info here.

Where and how do i check for fuel pressure?al - 1990 Toyota Pickup - Engine - 2/2/2013I am having problems with my pickup. It will not start unless I spray a little starter fluid. once it starts it idles ruff and when i drive it it has no power. I am thinking its a fuel pressure problem. It dose not have a fuel pressure check valve on the rail. So I ...-
2/2/2013 JimmIf it is a fuel pressure problem; it could be caused by a clogged fuel filter, or a bad pump, or a bad pressure regulator. Try replacing the fuel filter first. If that doesn't help, check whether the pump motor runs when the key is first turned on. If you can hear the pump running; then do a fuel pressure and volume check. The fuel line can be disconnected from the fuel pump to perform this test.
The pump should supply at least a quart of fuel per minute (8 or more ounces in 15 seconds). I don't know the pressure specification off the top of my head; but it should be at least 30psi. If the volume is OK but the pressure is low; the fuel pressure regulator is probably bad. If the volume and pressure are both low; the pump may either be bad, or it may not be getting full voltage (possibly due to a corroded ground connection, or corrosion in the fuse block or a harness plug).
You can confirm that it is a fuel supply problem by (with the engine stopped) briefly disconnecting the air duct hose from the throttle body, and spraying a bunch of starting fluid into the throttle body while the butterfly is held part way open. Then release the throttle butterfly, quickly reconnect the air duct and try starting the motor. If the motor now runs significantly longer before it quits; then it is a fuel supply problem. It also may be that the cold start injector is not receiving an electrical pulse; or that the injector itself is defective. If the motor starts, but doesn't run much stronger or longer; then the mass air flow sensor probably needs cleaning. Spray the air vane in the MAF with CRC airflow sensor spray until it is clean and moves freely through its entire travel.
2/2/2013 alSorry I should have stated, the fliter was the first I suspected and the first thing I replaced. The engine will idle after I spray the starter fluid to get it started, which is the only way I can get it started. If I do not spray starter fluid it will not start I will run the battery down trying to get it to start. After it starts it will idle all day and is responsive just ildes ruff. When I drive it it is terrible. It has no power and will sputter, I have tried to drive it at both low and high rpms but does not matter. Now you say I can check volume, so the pump will continue to run if the key is turned on?
2/2/2013 alI did a continuity check of the MAF assembly per the haynes repair book and there was 287 ohms between the points. Where is the air vane of the MAF?

When is the recommended time to change timing belt?charlyroae - 2004 Toyota Camry - Engine - 1/31/2013-
1/31/2013 Joe BoulayHello
Your engine has a timing chain not a belt. Keep your oil changed to reduce chain wear. Hope this helps.

What is the best way to increase the horsepower of my 2006 Tundra 4.7l v-8?Neil - 2006 Toyota Tundra - Engine - 1/26/2013I am using it to pull a 27' travel trailer-
1/26/2013 JimmFirst steps - less restricted air intake and less restrictive exhaust system; with the basically stock engine you will notice a slight increase in HP. Be careful to maintain all the O2 sensors and emission equipment - and have the ECU re-calibrated as required. Be sure to optimize the stock engine with a thorough tune-up; fresh air and fuel filters, new spark plugs, etc. Then you may try the intake and exhaust upgrades - as least expensive methods to improve both the mileage and horsepower.
